1972 Silver Dollar

During the first few years of it offering NCLT silver dollars, the RCM did not enclose its coins in a capsule. They were inserted into a plastic "frame" and then placed into a clamshell holder.

So, these early coins were exposed to the elements from the start and many developed toning. I wouldn't be too hard on the dealer who sold you the coin as it is very common to see these coins without them being in a capsule.

Without seeing an image of your coin, I can't say how it easy/hard it might be to remove the toning without damaging the coin. Do you have an image you can share?
