Not sure if this is the right place to post this question.
The other day I had stopped into a coin shop that I make infrequent purchases and bought some ASE as Christmas presents and some 90% dimes. As I was wrapping up my purchases the owner of the shop made a comment to another customer that the only way to make any return in numismatics is to buy MS graded Morgan or Peace dollars and hang onto them for about 10 years. And that any one buying 90% is almost wasting his time.
I was wondering what the thoughts are on the topic.
