Save and Get An Instant U.S. Collection
Mystic's U.S. Mystery Lot is a stamp lover's dream come true. Selections vary, but each includes a large selection of U.S. stamps (on and off paper),Postal Stationary, First Day Covers, album pages and more. The one I examined included 10 packages of U.S. Year Sets, a large bag of unsorted U.S. stamps on and off paper, a U.S. #1820 misperforated "freak" and lots more.
You never know what your going to come across and that's the mystery and the fun!
