I recently picked up this 1989 Upper Deck Griffey double print error card and it got me thinking about other errors. This card is a printing error, the front is the correct Ken Griffey Jr. rookie card but the back is triple printed with the correct Griffey back with Chuck Crim’s (#501) back double printed on top and Thad Bosley’s (#591) front printed on top of both. Due to the multiple printing on the back you can see the printing stress marks along the top left side of the front.
Are all errors created equal? Is there one type of error that affects the price more than others?
With errors there are design errors like a misspelled name or the wrong birthdate. There are printing errors like a double print, weak ink/discolored or blank back and there are manufacturing errors like the incorrect relic inserted in the card or when a memorabilia or autograph card is missing the relic/autograph.
