I do have an opinion regarding the matter of multiple strikes. There is no reason to believe that all countermarks served the same purpose. Using a great deal of imagination, I can list these (you might think of others). 1. Test to see if fourree 2. "I, (insert name here), have tested this coin and found it to be of good metal." 3. This coin has been sacrificed at the temple of (insert god name) and can not be accepted again for sacrifice. 4. This coin belonged to (insert name) who will prosecute any thief found with a large number of them. (I have seen merchants decades ago that put a pen mark on the large bills in their cash register for this reason. Anyone here know what I mean by a 'Hawaii' overprint US bill?) 5. This coin was weighed and found to be underweight and only accepted at a discount. I do not claim that any of the above are true meanings for any mark but I do maintain that we can not assume that each and every mark was for one purpose. Obviously some marks may have been for multiple reasons or always applied together (study required for that one). These are coins suitable for collectors who see the IM coin as especially interesting rather than a AG piece of junk with a lot of post mint damage. When I am buying a coin like this, I do expect to get it at a discount because the majority of collectors want pristine and beautiful rather than interesting with questions that may never have answers.
