Thank you for your thoughtful answer. I suppose I could possibly have a "superb" quality coin or coins somewhere in these sets, but I would not know how to identify it. With time, maybe even I could learn to recognize the difference.
I am new here.
I subscribe with the US Mint to purchase annual Silver Mint sets and America the Beautiful 5oz Uncirculated Quaters for my grandchildren. I see these same coins separated from their original mint packaging sold separately by coin dealers. I assume many of the coins are worth significantly more on their own than in the sets. Am I correct?
