This is a great video showing the process, I tend to go much slower and soak my coins for much longer and clean them over many sessions but the process is basically the same. He did a great job stopping at the right time, without a better microscope and other tools that was about as clean it was going to get without making mistakes.

Soft picks are made from wood, bamboo, or even thorns. Conversationalists hired by museums often use thorns. They're significantly softer than the metal the coins are made from and its much harder to damage a coin when cleaning with them.

• Thorns: They're put in a pin vise and used to pick away at the dirt. This can be seen in a video of depicting the cleaning of the staffordshire hoard (not coins) cleaning videos.
• Toothpicks: The first 5-10 pokes/jabs with them against a coin are decently effective.
• Bamboo skewers: I find them more effective than thorns and toothpicks and they're easy to sharpen over and over.

When it comes to cleaning with these there are two considerations, do you use them with the coin wet/damp or do you use it dry. Different cleaners prefer one of there other and my preferences often change. Sometimes wet appears to work better and other times dry appears to work better... I start dry and switch to wet if I feel I'm not making great progress.

As for how to use these... you can rub them along the surface. (its important to not bare down when doing this) or you can place the point against a "pile" or some obvious dirt and apply pressure to it. This can be risky even with soft tools and without magnification or experience you're likely to eventually remove features from the coin. This is unfortunate but inevitable, that is why its important to start with low quality coins while you build experience.

The reality is that soft picks are rarely effective when it comes to the coins I've received. I assume because all the coins that aren't encrusted with minerals and hard deposits were picked out from finds long before I have the opportunity to buy them. That being said if you don't have a microscope or some magnifier then these picks are really the best/safest tools you can use. If you use a soft pick to rub the surface between water changes then over a few months you can get a coin surprisingly clean. This is the slow but safe method to cleaning coins.

Is there any way to not have my Voyager browsing show up in my default browser (firefox) history. I do actually occasionally use my browser history to find pages I've looked at while browsing the internet... But my browser history is absolutely overflowing with hundreds of page views from using the "app". I know it's a web app but is it possible to have it use private mode (even better if I don't have to login every time I open the app if using private browsing).

This coin was minted in the Ancient Greek settlement of Selge, Pisidia. Coins of this type are from approximately 200 BCE to 100 BCE. It is a very small coin measuring in at 11mm and 2.01g in weight.

The obverse is a very off center portrait of Hercules wreathed with styrax, wearing a lionskin around his neck and a club over his shoulder. You can make out the lionskin clasp, the right eye is all the way at the top in the center, just to the left and down a little is the wreath. The reverse is the best part of this coin and has made it one of my favorite coins I've cleaned so far, it is the front of a stag looking back as it runs (presumable from a hunter). The greek letters Sigma (Σ), Epsilon (E), lambda (Λ) are the first 3 letters of the city Σέλγη • (Sélgē).

This was a great coin to clean, as I was working away at the layers of dirt I decided to leave some of it in place as an artistic choice. I really feel leaving some of the dirt in the field provides contrast to the heavily warn lettering and the stag. I cleaned this coin without knowing what to expect and the obverse was especially challenging because the portrait didn't make sense. It looked and felt like a blob as I was cleaning it. When 'digging' into the eye I was second guessing myself but experience was telling me it was fine. After identifying coin i can see why it was so confusing... the portrait is extremely blocky. In hand the obverse looks a lot better and you can make out more detail than the picture shows. I tried to get as much detail as I could when taking the picture but the 2D nature of the photo really doesn't do it justice.

I was not able to find an exact copy of the coin online but i found many extremely similar ones here. With the most similar one being SNG vA 5286 I'm mostly familiar with Roman coin attribution so I don't really know what SNG vA 5286 means... if anyone knows and can explain it please do :-) I think its a reference book and entry number

I primarily use glass containers. I figure glass is less likely to leach anything into the water & reduce the effectiveness of the distilled water as a solvent. I also have an affinity for glass containers and find them satisfying to work with. I use containers I purchased from a kitchen store that I believe are intended to be used to store spices. They look like this:

They're water tight and the rubber seals come in different colors to help differentiate one from the other. I put a paper label on the top where I write the type of coins, the count, and the batch number (row number in the spreadsheet I use to track cleanings, soak time, and last water change date).

What type of containers do you use?

When I was a child, my family moved to the woods where our house relied on a well for water. Unfortunately, the well water didn't taste very good; consequently, my father decided to install an RO system. Discontent with the upkeep cost of the RO system, he bought a countertop water distiller, similar to this one. You fill it with a gallon of water and sometime later you get a gallon of distilled water that tasted significantly better than the tap water. We would then transfer this water into a jug (with a tap) and store it in the fridge. Growing up drinking water from that jug, I developed a preference for the taste of distilled water. As a result, when I moved out, I bought a countertop distiller, which I continue to use today.

When I started this hobby, I was pleasantly surprised to learn that distilled water is arguably the most utilized tool in the field. I had virtually an endless supply on hand. Distilled water is an excellent tool for cleaning ancient coins. It serves as a gentle solvent that doesn't damage the coin but allows many of the deposits on ancient coins to leach into the water. This process softens the deposits, making them easier to remove. However, the water must be replaced regularly as it works best when fresh. This is because, as minerals and compounds dissolve into the water, it becomes a less effective solvent, and eventually, the water and deposits reach equilibrium. It is commonly suggested to replace the water every few days. However, I tend to replace mine every few weeks to once a month, due to either forgetfulness or a lack of diligence.

• How often do you change the water in which your coins are soaking?
• What is your source for distilled water?
• Do you use something else for long-term soaks?
• Do you soak your coins at all?

Some of these were so dirty, I was wondering if they were even really coins at all... These were the coins I learned the art of cleaning ancients on (and a few other batches of the same size/condition). Only a few were identifiable... I like to tell myself I'd do better cleaning these with the experience I gained from cleaning them, but honestly I now-a-days I probably wouldn't even bother. Which is probably why these were sold by the pound lol

I hesitate to post this coin because I really butchered it. It was among the first coins I cleaned and I followed some advice I found online that led to my stripping the highlights down to the bronze beneath which is a HUGE no-no. I still adore this coin because it was the first coin I cleaned that I was able to identify. So many of the ones before it were featureless. I call it my chocolate coin because the patina is a rich brown color. Despite my butchering the coin I find it aesthetically pleasing and it holds a special place in my heart. I really hadn't learned how to photograph coins yet when I took the before/after pictures here. You can see progress in my leaning coin photography by seeing the difference between the before/after here and some of my more recent coins I've posted. You can find out more about the coin here: RIC V 715

When I first started cleaning Ancient Coins, I bought a bag of "practice coins". They're coins in such poor condition that they're sold in bags by the pound. The vast majority of the coins are almost completely unidentifiable. I spent a year cleaning every coin in that bag (over 100) learning how to clean coins without damaging them. This is the best coin in the entire bag. I find it neat because its a coin made to celebrate the famous city of Constantinople. This particular coin was minted in Thessalonica (Greece). If you don't know Roman history then you might find it strange to see two kids being suckled by a Wolf but this is a symbol for the city of Rome and the two kids are Romulus and Remus which is from the story of the founding of Rome. On the obverse is Roma the "personification" of Rome. Normally coins of this type have two stars above the wolf, but I only see 1 on this one. I don't know if I have something special or not but I doubt it. You can much better examples of this coin here RIC VII Thessalonica 187

Its tempting to only post the best results or coins that are my favorite, but I think its important to show that the results aren't always great and you end up with a meh coin. Although the vast majority of the patina is preserved on this coin, its so warn that you can barely make out Minerva on the reverse. The coin looks better in hand. I do like that the lettering is easy to read on this coin and you can easily make out CAESAR just above Claudius's head. You can find many great examples of this coin here RIC I 116 or even on here with the other coin of this type I have.

Despite there being little to no detail to this coin, I'm still very fond of it. I'm actually proud of myself that I was able to attribute it at all given how warn the coin is. The obverse depicts Emperor Tiberius is considered one of the great 12 Roman emperors. The reverse has SC in large text which indicates it was minted and distributed under the authority of the roman senate. Better examples of this coin can be found here: RIC 1 44
