Can anyone here tell me how certain coins would be classified within the ISRI framework as defined by "Scrap Specifications Circular" (You must be logged in to see this link.)?
For example, let me choose three hypothetical coins:
All coins are 0.5" dia., 0.2" thick
Coin A -- Cu 100%
This seems to be No.1 Heavy Copper, code "Candy"
Coin B -- Cu 97%, Zn 3%
This seems to be No. 2 Copper, code "Cliff". The fact that this less than 100% Cu and more than 96% Cu, seems to make it #2. However, the spec also says "unalloyed." This confuses me. Wouldn't this be considered a CuZn alloy? If so, seems like it can't be #2 copper.
Coin C -- Cu 97%, Fe 3%
Same as Coin B. EXCEPT that it contains Fe, and the spec says "free of the following: ..., iron, ...". Does the fact that Fe is present mean that it can't be #2? If so, is it then Light Copper, code "Dream"? It IS > 92% Cu, and (I guess) does not contain "excessive" Fe.
Coin D -- Cu 60%, Ni 20%, Zn 20%
Here's where I really get confused. First question is, "Is this 'new' or 'old'?" If the answer is that the coins have been in circulation, so they are old, then the answer is simple, they have to be Old Nickel Silver, code "Malic". On the other hand, if they are New, are these New Nickel Silver Clippings and Solids, code "Major"?
Related to that, how would a new coin that just came off a press be classified -- new or old? How is this determination made and why?
Any help would be appreciated, as would pointers to any documents that explain how to make the classifications.
Happy sorting,
