Old Quarter Selling for Thousands on eBay

— -- Forget if the quarter is heads up or not. The important thing to look for is the fine print on the back.

Thanks to a ghostly date on the tail side, one batch of quarters struck in 1970 can fetch a fortune at auction.

One of these rare coins has been bid up to $35,000 on eBay, according to ABC affiliate WPVI-TV in Philadelphia.

The quarter is part of a batch struck over Canadian coins with the date 1941, according to Good Housekeeping. What makes the quarter valuable to collectors is an error: A “1941” persisted just above the word “dollar” on the back of the coin. It takes a very close inspection to see the date. The quarter on eBay is displayed in a case with a label reading “1970 S 25C struck on 1941 Canada 25C 5.63 GR mint error PF 65.”

It’s just one example of coins that seem like ordinary pocket change but could be worth a substantial amount. It might be worth that extra search under the sofa cushions.

Editor's note: A previous version of this story said the quarter had sold, but it is still up for auction.
