How rare is the 35s Anniversary Edition?

The original HP-35 had 35 keys, and I think that's why they chose that name. The 35s was never intended to be a "true" 35, if by that you mean a clone or a same-but-faster version (like the 15C LE was). It was the successor to the 32SII and 33S, very similar to them in many respects, but with a "retro" look chosen specifically to honor the 35th anniversary of the original HP-35.

Disclaimer: I think the above is correct, but don't quote me, because I ran out of coffee and I no longer trust anything my brain tells me.
