A good soak in acetone would probably do the trick, and without any damage to the coin. Acetone is a dangerous and volatile chemical, even though it is the main constituent to medern day `nail polish'. it should always be treated with respect. Don't get it on your hands or inhale it if you can possibly avoid doing so. Certainly never use near a naked flame unless you want singed eyebrows or worse.....

Warnings aside, it is a very useful part of any numismatic tool kit and worth
a try on your coin. The `green stuff' is probably actively eating into your coin (Looks like typical pvc damage to me brought about through storage in inappropriate PVC `flips' or sheets.

Thanks Ian appreciated :thumb: Need to ask though where would the best place be to get Acetone?

Now that's the very first bad advice I have ever seen Ian post.

Doesn't England have paint stores, hardware stores and/or home improvement centers similar to our Home Depot or Lowes? Those are all convenient sources for 100% pure acetone, containing no harmful additives, perfumes, protein nail conditioners, etc. A quart can actually isn't that much more expensive than a tiny bottle of the adulterated stuff sold as nail polish remover.

The distilled or de-ionized water rinse is still a good idea - just let the coin dry on a soft cloth and don't rub or pat it dry.

My apologies - I meant to post a reply, and inadvertently edited Ian's original post. Roy

 

LOL Ian I know i live in London but we dont realy have Alchamy shops and I thought that Scotland had advanced slightly too LOL do you know we dont even have a decent model shop in London either (I know I paint 15mm/25mm figs) think I might have to look on line mate

Wot...no model shops in the whole of London? We have one right here in Kirkcaldy. I think that must confirm it as being the metropolis of the north.

You could always get out the old school chemistry books and make your own batch. Just remember, no eye of newt required....or distilled lungwort but feel free to do a chant or two while the potion brews. Just don't drink it

Ian

 

LOL Nearest one is Colingdale about as far away from me that you can get without leaving London but not to worry got some coming from a hairdresser its neat as well so should work well
Have to ask the Mrs about a spell for making it she's the Witch :whistle:

Local suppliers are always the best. My last batch of home brew blew up (literally!). I think it was an omen telling me to stick to single malts.

If you have any difficulty using it / getting the desired result, then send me a pm.

I have 4 countermarked Mexican coins

8 Reales 1873CMP KM# 377.3 Many Chinese Countermarks
8 Reales 1875JA KM# 377.13 Zs , Zacatecas , A Chinese Letter Countermark
8 Reales 1878JS KM# 377.13 Zs , ZACATECAS , A Chinese Letter Countermark
8 Reales 1886MH KM# 377.10 Mo , MEXICO , Many Chinese Countermarks

The Krause catalog tells, Under the section on China / Anhui province coins , that Spanish American coins saw wide circulation in this province until the end of World War I. (page 383 , 1996 edition)

 

Do you have any pics ? I have not seen any of the Mexican ones but have heard about them
