Do you own a rare 1970 US Quarter? Congrats then you can sell it for more than $1000s now on ebay. Recently a rare 1970 Quarter sold for around $35K. The coin was accidently minded back of a Canadian coin. So it's a USÂ 1970 quarter on 1941 Canadian coin.Â If you own a coin like that will you sell or keep it with you? If you are so rich then will you buy a coin like that?
