Counterfeit Forever Stamps

This may have been true several years ago. But in recent years, every issue has been counterfeited, with the exceptions of stamps issued through ATMs or in Prestige Booklets. Angel's Trumpet is just one example.

More importantly, it's not simply that each issue has been counterfeited. Some issues exist in several distinct counterfeit varieties, which strongly suggests that they are being produced by multiple counterfeiting operations rather than a single source.
