No, you couldn’t get away with calling a modern $5 gold bullion coin a “Saint-Gaudens”, despite the fact that they recycled the old Saint-Gaudens design on them. If you say you’ve got a Saint-Gaudens, it is understood that you are talking about a 1907-1933 double-eagle. But you could call the modern bullion $5 gold piece with that design a “Gold Eagle”, even though it’s technically the same denomination as the pre-1933 half-eagle coins. That’s because, as mentioned, the modern bullion issues are all collectively branded (confusingly) as “American Gold Eagles” (AGEs). Regardless of their denomination. And yeah, the modern silver bullion coins are also called “Eagles”, even though they aren’t actually $10 gold pieces.
And there's a very low chance that anyone's going to have a 1933 Saint-Gaudens Double Eagle because of FDR's Gold Confiscation Act (I remember hearing about it multiple times on Pawn Stars and you posting about another one on the show that I haven't seen yet.)
If that was the case, I'd buy at least one of any other year of the Saint-Gaudens, all years + mints that Morgans/Peace Dollars were made, a few of the 50$ Gold Buffalo's, but that's just off the top of my head Also have to have at least one of the 8 escudo Spanish coins: https://www.ebay.com/itm/2966244754...uid=rYYw9bLoQeO&widget_ver=artemis&media=COPY
Been there, done that. Never thought I'd be able to, but after I came into a little inheritance in early 2022, I bought several coins I never thought I'd be able to afford. My coin collection is now worth more than my real estate holdings and my car put together. Which isn't saying much- except perhaps that my priorities might be a tiny bit out of whack. LOL. But I was at least responsible enough to pay off the mortgage and all the bills and cover my daughter's education first, before I went hog-wild on gold coins.
