As someone who collected baseball cards during the late 80s/early 90s, there were a few players who were always in demand. Mark McGwire and Jose Canseco. Ken Griffey Jr. Bo Jackson. Todd Van Poppel (no, seriously — one of my friends had a 1991 Upper Deck rookie card for the overhyped prospect who ended up with a career record of 40-52 and a 5.58 ERA and we all thought he had won Powerball).
But the guy everyone wanted a piece of was Gregg Jeffries. A can’t miss prospect for the New York Mets, Jeffries was the first player to win the Minor League Player of the Year Award from Baseball America twice (other players to have won the award include Dwight Gooden, Canseco, Frank Thomas, Derek Jeter, Mike Trout and the only other 2x winner: Andruw Jones). With his versatility in the field and undeniable talent at the plate, Jeffries started his pro career in 1987 with a bang and made an instant impact for the defending champion Mets. The hype train went into overdrive and his rookie cards became the hottest thing since Prometheus brought fire to the people.
So when I got the above Donruss card and noticed the coloring error, I thought I had hit the jackpot. Error cards can be extremely rare and valuable, so the fact that I had one for a player in such demand as Jeffries meant I’d never have to work a day in my life, right?
Obviously, things didn’t work out that way (for me or Gregg, who had a fine 14-year career, including some excellent seasons for the St. Louis Cardinals in the mid-90s, but will never be voted into the Hall of Fame). The value of error cards, and baseball cards as a whole, depend on supply and demand. And once it was clear that Jeffries wasn’t the second coming, demand plummeted and everyone moved on to the next can’t miss kid (Jeter, Chipper Jones, A-Rod… there’s always someone).
Error coins are the same way. Whether or not you have a Griffey Jr. or a Jeffries depends on supply and demand. Here are a few of the error coins I’ve collected over the years:
