I have an unopened box from the mint that contains a set of 1999 P,D and S sets What do you think this box is worth?
Assuming you have the 9 coin clad proof set, I would estimate the value of the 1999 Mint and Proof sets to be $80-$100.
So, what you really have are 3 1999 Mint sets. Valued at about $35 each in Coin World Values currently.
Just finished looking at these coins thru the "looking glass" , one RPM on a half D mint and a couple of coins that I am going to send off to be graded in a armoured truck.....lol
Well since they quit putting the mintmark on the dies by hand in the late 80's it can't be an RPM. Most likely it is a case of machine doubling. Speedy
