Found a Unique Coin Today But How Should I Clean It?

[nkellam22]

I found this coin while exploring a new site next to a creek in the woods near my home. I've identified it to be a liard from Luxembourg dated 1759-1760.

The problem is I don't know how I should clean it. Normally I just brush away the surface dirt and maybe a little toothpicking if needed but this coin looks quite fragile. Since finding it parts of the dirt has flaked away and I feel that if I remove the dirt on the surface it will wipe off all the detail but if I leave it it will happen anyway.
So what would you recommend I do?

I know the mintage is high but it's still a different type of coin I haven't seen posted on this website before.

Good looking coin, I haven't seen this one before. Since it's not necessarily a valuable coin, I would clean it with peroxide and than apply Renaissance wax on it.

I can't help you with the cleaning info. Surely, someone on here knows, though. pretty cool old coin, congratulations!

Thanks for your help. I like your idea involving the Renaissance wax but I feel the hydrogen peroxide might be too harsh as I don't know if the dirt is the only part of the coin with any detail. If you really think the hydrogen peroxide is a good idea ill try it.

Nice old coin recovery! In its condition, perhaps not cleaning it at all would be best.

I have found hundreds of old coppers that were damaged by the farm soil and cleaning would only make it worse.

All your choice peroxide warmed up in the microwave for 30 seconds works for me also a little soap and water some like to keep them as is athers want to clean them for details there is always a risk nut I would personally clean it up being its not a valuable (money) coin but would be nice to display
