Thanks for the responses and links. Here is a coin I'd like to open and put in my album. Do I treat it with anything when I break it free?  |

If you look you should see a thing called Search somewhere near the top of page. Try it and type in words like Acetone, coin cleaning, cleaning coins, etc.

I agree with Biokemist. Dipping generally refers to use of an acid-thiourea type solution (NEVER use such dips on copper!). Otherwise, we usually call it conservation when coin-safe chemicals are used. Water, acetone and xylene are examples of coin-safe conservation solvents.
Why do you feel compelled to dip a slabbed coin? The pictures aren't very good but from what I can see I wouldn't remove it from that old slab. It looks like a pretty nice coin.

This is a close up through the plastic. All my large cents are non graded in an album and this coin would fill the last hole. That would be the reason to take it out. Should I do so, any treatment suggested that would improve things without damaging the coin?  |

OH, now I see, garden variety verdigris. It doesn't look very old, you should have some luck with VC. Trying the regular array of coin solvents will be futile IMO. In fact, they may hurt/change the patina, this is a rich, dark copper coin. Hopefully the heavy spots have not eaten too far down into the metal. What does the other side look like?

Looks like that will clean up nicely with some VC

Looks like a nice AU-MS coin, worth the conservation effort with VC IMO. I think you'd be happy with the end results even if not all the verdigris is removed.

Can I buy that in Calgary, Canada or is there anyone in Calgary who has bought this and can sell me half a bottle?

Why not just try Acetone first. Should be able to buy that anywhere.

Keep in mind, the more things you "try" on a coin, the more you push your luck in changing the patina. I recommend jumping directly to VC to address the verdigris. If you want to start with something outside that, I recommend xylene to remove any oils or organics, the go to VC. You can order VC using the link in my sig. Wizard ships anywhere I believe. You can also use ebay and global shipping program. However, shipping outside the US is expensive. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Thank you BadThad. If I cannot find any collector or retailer in Calgary that could sell me some, I just might have to order from the U.S.

So I am switching back to my original question about acetone. Is this silver dollar a candidate for it?  |

I don't think using acetone on that coin will improve it in any way but I also don't think it would hurt it either. Acetone will have no affect on the toning if that question is on your mind.
