I purchased this in 1990 from an East Coast dealer who graded cards under the name of Acucard Inc. these cards were right from the factory, according to the seller and most certainly look like they are pristine and mint condition. apparently the company went out of business in 1992, but the cards are authentic and beautiful. I am not sure but it sent to a regular grading company. I believe the grades are accurate and would come out Mint 9 maybe a Gem Mint 10? not sure but these are great cards and you get the entire set of 12 cards. I see a PSA 8 NmMt Ken Griffey Jr sold for $399.99 on March 30 2024! Asking price on individual cards vary with some Griffey cards asking close to $1,000.00. This is the rare opportunity to get all 12 cards at once any questions please reach out to me.
