CHICAGO — The year 1970 may be your lucky number.
Check your pockets for a quarter made that year, because it could be worth a lot of money.
On the back — just above the word “dollar” — there is a tiny “1941.”
The mistake happened when the quarters were printed over 1941 Canadian quarters.
“This is one of the most fascinating and intriguing proof mint errors ever discovered,” the listing reads. There are currently more than 300 people interested in the item on eBay.
