Greetings! I am hoping to get some advice on what to do with THOUSANDS of mint, post office fresh US stamps. My dear father in-law collected books, sheets, zip blocks, plate blocks and all other forms of stamps. The Zip blocks and plate blocks are neatly organized into albums, but there are quite literally thousands of stamps either loose or in the shrink wrap from the post office. There are many denominations, from .05 to forever stamps (more than I could use in my lifetime).
I have been considering selling lots on
ebay (how big should the lots be, should I group like-category stamps?). Any other suggestions?
Thanks in advance!
