Oddball SBA Dollar- Wrong Planchet?

@ Bobby:

Two of the best say is missing, so is missing.

The table I put represent the clad strips before cladding. Missing me the inner dimensions strip. So this dimensions of the clad strip will not change during the Clad rolling. During the Clad rolling will be thickness change and also flow of the material. I do not have all the data in order to math correctly. Brand do a great job equating on relativity. If him has all the data will be much easier for him. In order to calculate more or less accurate the inner strips specs are required, and I do not have those.

All those calculations must be done on Pythagoreans equations, which it is use in the science at all levels. More further studies (destructive) of those clad coins must be done in order to know exact the weight of the finished product components.

I still be skeptical about the weight of this coin but if was categorize as missing one side of clad is OK.
