There's actually two different Padres balls. One with the Pentagon and another with a Homeplate shape. Still looking for that one LOL
Can you tell me where you found that Grinder's Cup image? That's actually not the ball I was referring to. This one is:
Well some have been ebay purchases, but the majority were trading with others. There's a close knit handful of us that takes cares of one another. A lot of these are from private clubs or events. We go to what we can, get as many as we can, and trade with guys who did the same thing with a different one. My collection got started out of the kindness of some guys who just gave me a bunch to get going.
The secondary market is just plain stupid and not needed. Yes, you may never get a Whalburger ball, but 80% of the collection I have is from flat out trading. Stars and Stripes can be found in retail easily right now at normal Chrome Soft prices.
Don't forget about me LOL
