PSA Graded Base Set Booster Packs - 1st Edition Error 
PSA 8 Graded Charizard - only 4 in PSA pop report
PSA 8 Graded Blastoise - only 3 in PSA pop report
PSA 9 Graded Venusaur - only 2 in PSA pop report

Some 1st edition stamps where accidently printed on the unlimited booster variant. A black triangle was used to cover the 1st edition stamps. However some made it out of the factory before that black triangle could be added. From what I can research there was only one box of these known to exist and the packs where sold off back in 2013 (I bought some). There is a good chance a lot of them have been opened/lost since Pokémon did not have as big of a following/knowledge as it does today. Below is a great link from a highly reputable source about these packs. Go to the 2:40 mark.

These are easily the rarest base set booster packs in existence. These are so rare PSA did not have them in their system. I had to file a grading error, and PSA created a brand new category for these packs; they are so hard to find I might be the only one with all three artworks graded. If you want to be the guy/gal with something virtually no one else has in their collection, this would be a great lot to have. 

Because of the value, I will only ship this to established eBay accounts. I will cancel any and all transactions for new or fairly new eBay accounts.

ANY ATTEMPT AT FRAUD WILL BE APPEALED AND LEAD TO POSSIBLE EBAY BAN AND/OR ARREST! I WILL CONTACT YOUR LOCAL LAW ENFORCEMENT AGENCY TO FILE A FELONY POLICE REPORT AND PURSUE ANY AND ALL LEGAL ACTIONS.
