What it's worth when you sell
Struck only in 1966. Its 80% silver content was soon worth more than 50 cents, so it was withdrawn; the 12-sided copper-nickel 50c replaced it in 1969.
Common dates usually sell to dealers for around their melt value; scarce dates, mint marks and coins in top condition can be worth much more. For a valuable-looking coin, check a price guide or have it graded before selling.
