Anthony's seems to be at it again. You can purchase the case stamp and 10 coupons for 190 Proof Alcohol from Anthony's for $100.

Or you can purchase one just like it from Eric Jackson for $15. Hardly a scarce item. These are all from the National Postal Museum's disgorgement of some of its enormous holdings of obsolete revenue stamps that had been transferred to them by Internal Revenue.
