The listing, USA #2361 1987 CPA stamp (scarce), mint has ended.
USA stamp commemorating Certified Public Accounting.
This is one of few modern US stamps that is worth more than others issued during the same time. The reason is that a CPA related firm purchased a large quantity of these stamps for their use (either mailing or give-aways); this makes relatively few available to the stamp collector market.
Year: 1987
Catalog # 2361
Condition: full gum, mint never hinged, post office fresh
I have several of these stamps, all identical, the scan is representative of what you will receive.
