+1 to all. My opinion as well that Roz signed the DF material.
As bad as they are, I was trying to mitigate the blow to avoid losing Robert. Maybe offer a shard of light at the end of the tunnel. The forgers not only devalue the real thing in the minds of people able to buy them at 1/2 to 1/4 the going rate, but can make a buyer feel like a patsy, thereby alienating them from what should be a wonderful hobby for them.
The forgers give them away because they'll just replace the inventory from the bargain box and then at the kitchen table.
