yes there are! There is a giant base set Pikachu that you could have had your picture taken in front of at their mall tours back in 1999. There is a photo of one in the unofficial Pokemon player’s Guide. I believe the Riachu was from the original team rocket set…i have never heard of the mewoth though.
I only know of a couple people who own the Sneasel…and good luck getting one. As for the others, my best guess is that wizards may have kept them…or at least to the best of my knowledge no one owns them??
I believe DJ had said that Pop had all 4, but sold one to crazypokemon, gave another to Gym Leader Blaine, and then at the time of the post, he was unsure if Pop still had two or just one. (This was in February).
I emailed Pop (his Gym inbox is full/blocked >.>) and I am awaiting a reply.
There are the jumbo trophies. I can’t tell if they are just a poster or a jumbo card the the others. I believe there is another view of them in the Official card book 2000 but I don’t have the time to check.
