US Stamp Collection Value.

PSE 80 is a nice set of Zepps, but it is not going to bring the higher prices. For that you really would need a 100 score to be thinking in terms of getting close to the catalog value, or a 90 to get you in the $1,000 to $1,250 range. A PSE 80 would likely get you something around $800 but then you would have to deduct the auction fees which tend to be substantial in most auctions (the typical is 15%, plus your shipping costs and sometimes listing or other fees which mean an $800 selling price might bring you a check for perhaps $650)

Here is a never hinged set that sold for a little over $900 early last month.

The prices on the Zeps are trending downward.....pretty much like all stamps.
