Ok so at this moment am out and about. Cannot post pictures at this moment but will later. Was wondering how to identify if indeed I do have a 1964 SMS Lincoln. Thanks. Dusty
One of the easiest diagnostics to quickly rule SMS out is the rims. SMS Cents will have sharp, almost proof-like rims.
You may have a 1964 cent from a proof set. Here is an example. The easiest way for me to tell the differance is that the field has more of a smooth mirrored finish look than regular business strike examples show. 1964 SMS sets are extremely rare. Here is a link that may help you. Pictures would certainly help us http://www.coinworld.com/Articles/ViewArticle/1964-sms-coins-are-enigmatic
Pretty sure it is just a proof. After looking at my other SMS's still have a gander though if you need more pics just let me know Dusty
