13 dollar coins from 1970's and 8 half dollars most from 1970's and one from 1964. I was just wondering if they are worth face value or what. Thanks.
1964 half is 90% silver (about $10), 65-70 halfs are 40% silver (about $4). A few Ike dollars are silver if 71-76 but not the normal circulation coins. Check this site http://www.coinflation.com/
Sorry, but the dollars are most likely not silver. The only silver ones were issued as collectables. For the halves, the 1964 is 90% silver, so it has about $10.33 in silver in it. Any half from 1965-1970 is 40% silver, containing about $4.22 of silver. The rest, you might get a buck for if they're in nice shape
Wrong. They're worth face. Keep the silvers, keep the ikes, because they can sell for a premium on ebay if you have enough, but the rest of the halves (1971 and later), cash 'em in.
