I inherited a few of these. Long story short they are dirty not from aging or use but I believe road grime as they were hidden in the the vents of a truck. I've done some research on cleaning coins, general consensus is don't ever clean a coin! What suggestions does the community have for my situation and preservation of these coins? I'm assuming I'm not going to get a premium if I decide to sell these due to the condition. What should I expect? I've included some pictures of the coin and holder it came out of. Sorry for the bad lighting. Thank you all in advance, you all have been most helpful so far with excellent advice! View attachment 1006094 View attachment 1006095
