The only thing I ever heard that wouldn't damage the coin's value (and you) was a soak in vinegar/water mix or olive oil overnight & pat dry.
There is no best and safest way because each coin is going to be different, have different things on them, if they have anything on them at all. And it is whatever it is "on them" that determines what you use to get it off - and if it is wise to even try to get it off ! In other words, rather often your best option is to just leave the coins alone and store them properly.
Short and sweet Sal your question is exactly the same as every other question about how to safely and properly clean coins. And so the answer is the same 4 basic ways that there is for any coin.
1 - distilled water
2 - acetone
3 - xylene
4 - coin dip
Maybe olive oil, and that is questionable on certain coins.
Definitely never use vinegar or hydrogen peroxide. They both will etch a coins surface.
Oops. I forgot that vinegar contains a bit of acetic acid.
How do you make the 'coin dip' ?
...uh...vinegar IS acetic acid (usually 5%).
@SensibleSal66 was going to send a PM, but you might have disabled it for some reason...I see others commented this too. This is something that is more usual in the Ancients Forum with old bronze. There is a product called Renaissance Wax (or Ren Wax for short) that will somewhat fill and seal porous coins. In lieu of that, I have used linseed oil. Linseed oil is what is used in "oil" paints, it reacts with oxygen in the air to form a plastic that will seal the surface. What you can try is 1) soak the coin in distilled water with some brushing with a toothbrush to remove verdigris that might be present 2) treatment with organic solvents would be a good thing if you can stand it...acetone or xylene, outside if you are concerned about vapors 3) dry the coin thoroughly either in an oven or letting it sit in hot sun for a few hours 4) put a drop of linseed oil on each side and thoroughly massage it into the pores of the coin, wipe off any excess and let it sit. Try this on one you have given up on. Good luck.
You don't make it, you buy it. There are numerous commercial brands on the market.
Hey Kentucky..... A few years back I bought an ancient Chi-Rho that I had made into a nice necklace for my wife. The Chi-Rho symbol is all over our church and she likes that sort of stuff..... Anyway after six months of wear the coin became dull and dead looking. Is Renwax what I need to use to put some life back into that ancient?
And my deepest apologies for the de-rail...
