ive been a coin collector for 40 odd years and i have never even considered this. i will stand on the side of melting, but only if were talking fair/fine coins as im a great believer in the preservation of our numismatic heritage. i would not want to melt a good piece just because its metal value is more than its value as a piece of history, the coin collector in me is fighting that......I think that may be an easier decision to make if i were a coin dealer however as turnover/profit comes into the equation. I have 1966 and 1967 coins in my collection and more besides, pennys halfpennys dodecagonals and as much as serious collectors may feel their of no numismatic value, i treasure them, as an 8 year old entering the hobby, they were my first coins, metal values may exceed their value.....but their mine and have been for over 40 years.   my sons can fight over who melts them when im gone
