-- 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.
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.
