Things did break for me within the last couple of weeks, as I located two cards from Herschel's playing days, which I did not have previously. One of these is a card I knew nothing about until a new space was created for it on the Trading Card Data Base. The other was a parallel from a set, which I was aware of, but was never able to locate. Though these two cards were not on my most wanted list, they could have easily made the grade.
While I await these cards in the mail, I picked up a 2019 Score Buyback card of Herschel off of EBay.
The way the Buyback gimmick works, is that a card company, in this case, Score buys up original trading cards on the secondary market, and in most cases marks the cards with a special stamp.
Usually this is done for an anniversary of some kind. In this case, it's the 30th anniversary of the original year issue.
The stamp can be seen right above SPEEDBURNER on the card front. This subset featured some of the fastest players in the NFL at that time. The total # of cards in the set is 440, which of course, was the total # in the 1989 set.
Herschel has two other cards in the set. #34, and #331S. The feelings are mixed on buybacks. Many collectors dislike them, as they feel they the stamp mars the original card, and that it's just another chase gimmick, which it kind of is.
As a single player collector however, the chase is what it's all about. If you're realistic about the fact that you'll never own everything available and you watch your budget, adding different cards to your collection, no matter how slight the difference, can be fun.
