Don't forget the 2008 sets, the clad proof and silver proof sets have a good premium also.
Not sure what one would sell for. But I am pretty sure it would be hard to put a Dansco (two album set)
State Quarter P,D, clad S and silver S plus territories for under $600
With silver trading at around 30X face. 56 silver quarters would be
$420. Add in the premium for the 1999, 2001 and 2008 coins.
I also do not think you could get the P and D quarters in BU condition anywhere near face, unless you knew someone who would
let you have them cheap. I would say most of them would be 50 cents each with some in the $1.00 range. So the 112 clad business strike coins would be $56 to $70. The 56 clad proofs I think would cost more in the $75 range. If the sets were in Dansco albums another $40+.
After seeing these numbers I changed my mind, I don't think you could put a complete set of quarters 1999 to 2009 P,D,S,S in Dansco albums for less that $800. I am counting having to buy the 1999, 2001 and 2008 proof sets to get the quarters.
