Tom Boblittthey could be easily faked. I don't just think a stamp with a stamp pad stamping on the back of these cards would do the trick. If you've used a stamp pad before, the ink quality isn't consistent across all areas. Just isn't. These overprint Play Balls were printed in sheets used for advertising I'm sure. I've had probably a couple dozen of them over the years. May have a couple laying around right now. Not sure. Like has been previously said, the normal Play Balls aren't really THAT valuable and these might add a little premium to the normal price. I guess I can see someone MAYBE faking a DiMaggio but to what.....gain a couple hundred bucks? Or maybe ruin a good DiMaggio. Not like an E94 overprint back where the value goes up 20X or some multiplier like that. Plus the backs of the 39 PB's are REALLY porous paper and I bet if you used a normal stamp it would really bleed into the paper.
