Its a threepence from Great Britain - it has three acorns on it - I have never seen one either but my coin catalogues identified it for me so now we all know! If I am correct they were only minted form 1927 through to 1936 with the 1927 ones only issued as proof coins....just as well I only collect pre 1921 British coins otherwise I might go gaa gaa over it!

before and after shots. ammonia and vinegar. day in household ammonia and then an hour or so in vinegar then back to a day in ammonia. still have some more ammonia soaking to do to improve the other side of the half crown. It has an area with a red brown stain which is resisting my efforts.

Had a bit of a disaster while cleaning with ammonia; I had 20 or so silver coins soaking and threw a little Saint Christopher looking thing in with them. I am not sure what it was made of (not silver) and it turned black and had all this black mossy looking stuff growing off of it. It had a curious effect on the coins, and not a good effect. They changed colors and I have worked with minimal success getting them back to a normal looking tone or a silver looking shine. I now have quite a few pinto stained things with partial off-color tone and off shine and some that are toned on one side and over cleaned on the other. Very few of them look acceptable. So I guess the take home message is not to throw other crap in the cleaner with good coins.


Another experiment I did was to fill my tumbler with walnut shells and tumble some pennies. I used to do a lot of reloading and used crushed wallnut shell to clean fired brass in a vibrating tumbler. So I figured it might clean up pennies without knocking the patina off. I ran some overnight and it did a reasonable job of cleaning them up, but the edges were getting nicked up from banging into each other so that didn’t really work out.

I have been using a cheap dremel type tool, with felt attachment wheels and Autosol polish. It cleans up the spendable coins like new, and if you go lightly (don't overdo it) it cleans up the older coins to shown some detail and remove most of the stains. It doesn't take long and after a while you get a good idea how much they need. Probably shouldn't go near anything rare and valuable though, and if the Dremel comes with wirebrush attachments leave them in the case!
There is probably more experienced people out there that will cringe at the idea
