This is a cover I bought on a whim. It doesn't fit my collection, so I want to re-sell it.
All 14 stamps, the omnibus and the long set, postmarked Sandy Point to Robinsons.
I've looked in Unitrade, googled extensively, and checked dealer sites, but I can't find a FDC value for this long set. Can anyone help with a guide to value so I can sell it with a clear conscience??
