That is news to me, but you may well be right. But I would have thought that the specifications determined by the mint are for the most part obeyed, though. Once the die is cast, etc. Plus a uniform coinage was understood to be paramount for a new nations reputation in the world, so it's not like there was such a hit-or-miss situation with diameters.
With CB Dimes the diameter went from 18.8 mm down to 18.5 mm in 1828 -- a 0.15% alteration. The sloppiness in the album manufacturing is a whole other degree of magnitude.
