it says none minted for general circulation , there 1970's mint with the D mark... 1958 mint pa set... 1971 eisnhower mint dollar.. stacks of 76 1/2's and 25 cents...
??? only the Silver Ike was not put into circu;ation. I do not know of any Denver mint coins not being circulated in the 70's.
What you have is simply a set of uncirculated coins that someone made up. All of these coins were minted for circulation in 1970, so the value is really face. I'm speaking strictly about the '70-D set.
The 70 d 1/2 wasn't issued for circulation. The cent has copper value, and the nickel has nickel value, and everything else is face. The Half is worth around 15.00 * d.t. posted while I was typing
The 1958 proof set is valued around $45-$52.50, The 1970 set, whatever it is, looks like it was put together from business strikes taken from circulation or bank wraps and place in a multi-holder. As for the NONE MINTED FOR GENERAL CIRCULATION disc, that space was for an Ike I think as it looks larger than a half.
