It looks like the bare belly to me, though not the most dramatic example. On some of them the beaver's belly is completely gone due to over die polishing. Normal nickel on the left, OP's nickel on the right. Here is an an example of a bare belly nickel (Not my photo)
Yep, that's definitely a barer belly than my example. There's a whole range of bellies, depending on how enthusiastic the die-polisher was.
I only know of the 1990 Bare Belly, and they go for 5 to 10 times as much as the regular ones--not as much as a real rarity, except for the higher MS grades, which are insane as usual.
Just found a 5 cents 1934 "far S" (or "far rim"), the kind of minor variety we hypernerds just love (because it's not real expensive)....
The nickel I posted at the top of the thread was called a "#5" bare belly. I don't know whether that's more, or less, bare than #1 thru #4, but obviously there are at least 5 degrees of belly-bareness.
