It appears the Mexico Onza pre-1982 have disappeared from the “1 Onza” listing. I have a 1980 Onza that showed up as my largest coin, and now it's the American Silver Eagle. That's how I noticed the page went missing.
Yes, we need to come up with a solution for these pieces. They are neither full coins and also are distinct from other bullion by being exchangeable.
Perhaps it is necessary to add a new type of coin, on par with “Standard Circulation” and “Pattern.” Of course, this discussion should take place in another thread.
