Hey guys I pulled out a box of my silver bullion that I’ve had in my safe since 2015 and sadly I noticed that a lot of the 1oz silver bullion rounds that were kept in APMEX plastic flips have tarnishing on some part. Most of it looks really ugly and I’m wondering if it’s ok to clean them? I know with numismatic coins cleaning is a bad idea but what about bullion? All of the rounds are 1oz silver national bullion coins: - Canadian Maple Leafs - American Eagles - Mexican Libertads - British Britannias - Chinese Pandas - Australian Kookaburras - Somali Elephants - Austrian Philharmonics Stuff like that. If anyone could advise me on this I would very much appreciate it. Thanks! P.S. If it is okay to clean them what should I use?
Get some of that silver dip from Walmart. A few seconds makes them look great. Rise with clear water after.
No Acetone does not affect toning on a coin. Its a solvent that devices organic residue, dirt, etc. Check out some the recent threads regarding acetone. I think each one has at least a couple posts saying this
Personally, I would get rid of everything except the American Silver Eagles and don't touch them! Toning is okay, it's not gonna affect the price you get for them so leave them alone!
A quick dunk in this then rinse well under running water. Pat dry.This should work well if the toning isn't too advanced. Don't leave it in too long, or you will burn the luster off your pretty coins. Start with pieces that have no premium so you have nothing to loose. Also, sounds like you will need to find a better storage method.
Back in the '60s, my dad would wrap his coins in thin aluminum foil sheets. I unwrapped some that hadn't been opened in 50+ years...and they all looked great!
