So.... I sold a Kennedy half error on ebay for $40. Bought $2 face of 90% on ebay....got my coins yesterday. Included were 2 mercy's.....both 1925-s. One is very good..and the other is extra fine.....coin guide says $100+!!
I'm no professional, but I'd say thats closer to VF than EF (plus its damaged). Regardless, its a very nice coin to come out of a junk silver purchase.
