Since the Bullion Silver Eagle has no mint marks & has been primarily minted at other Mint locations over the years. With all the supplement issues having a mint location in parentheses (P), (S) ect. on graded examples. I have noticed the (W) "minted at West point" is being put on slabs for every year, along with other slabs without anything on them. Even the registry has a spot for every year of minted in west point & regular Bullion no mint location. Aren't they both the same coin from the West point mint? Isn't the west point mint the primary mint making these? Also in the census report, it shows that all the bullion coins as being minted at Philadelphia mint from 1986 to present.
