I was in my (I'm sure the owner is surprised it's not his anymore) coin store yesterday, and they had a few of the Mint Sets. There is a definite difference between the uncirculated stuff I've already bought, and what's in the Mint set. My dealer saw the difference, as did another dealer I recognized who was in there selling coins. I can't describe the difference, other than to say the Mint Sets look significantly better.
Will there be different pricing for individual mint set coins than the circulation strikes? Wouldn't the mint set coins now be condidered a variety? I don't think the mint sets should have changed. They should have remained the same as circulation strikes. hence the name uncirculated set.
