The highest priced proof set since 1999 are the 1999, 2008 and 2012.
The 2008 and 2012 are the highest for the clad sets.
For 2008 both the clad and silver quarters did come in separate five quarter sets.
I always check the site "coins by bobby" just to get a price range.
He has the 2008 five clad quarter set for $49.00
From my experience ... Plan on paying more for the 2008 proofs then you
would for other years.
Edit ... I forgot to say, if you can get a clad quarter set for less the $20.00 I think you were getting a good deal.
