Should I clean the ones on bottom 3-4? If so how? There is a dark mold? growing on them. I have in same holding spot as all the rest but only those did this. Also if I sold the 2019-2021's as a set what would be a good asking price? Ty for any info. ENJOY. Sorry pics from phone .
Do not try to clean any of them, no matter what. If there’s haze on them just sell them to someone who doesn’t care.
Sell the cat, all it does is sit there and watch judge judy anyways. if those are just bullion eagles, not proofs, not the special uncirculated ones, leave them as they are, wait for silver to go up and sell them, then buy clean ones to replace them with when the price drops again. an oz of silver is an oz of silver. if it's not like one of the proofs (and it's not) or one of the burnished SAEs, it's going to be bullion price anyways. wait for an opportunity and sell them off and then rebuy nice ones on a price drop and let someone else deal with cleaning if they want to.
Wouldn't clean...sell 'em off easy, maybe to your LCS or swap shop/silver buyer and be done with them, then I'd invest in better ones (only two...? no matter).
Leave the coins alone and add to the collection. You want something to clean, try the fridge and then the bathroom. Just saying, you can't hurt cleaning those areas.
The ones you don't like, place on to a south facing window sill and allow them to bake for a month or two (turning them ever so often). Upon the achievement of spectacular toning, market them on ebay and walk away with ga-jillions. Or.......do what everyone else replied above.........leave 'em be.
