Two Feather Buffalo Rarity List

Reviving this thread, with a humble pass by myself, 1buff2many & Ty2020 to modernize the 2006 rarity scale from the late Ron Pope - based on not only the updated graded population but also our own picking and personal non-graded 2F
collections. Hope this is helpful for those who have caught the 2 feather buffalo bug. The URS scale for reference can also be found below. Our counts include data through late 2023 and include 2+F and 2HF.

I found these at coin shows / online auctions. I also look through Whitman folders for them and buy the whole lot if I have to - have done that a couple of times. Still looking!

two that I have---

@Tonyqt would love to see a photo of that AG03 1923! So few can be found, it would be a great reference point.

@mikev50 was your 1913-S won a few months ago at a Heritage auction? If so, I was bidding against you on that one! Capped out on what I was willing to spend, but the final hammer $ was still approachable given the rarity.

If 2 Feather varieties got half the attention of the 3-leggers... maybe some day.

Here is the 1923 2 feather I have.

I put Acetone into small used (and cleaned out food jars with a metal twist lid - BUT because of the sealing material inside the lid, I wrap it with tin foil so the acetone fumes won't interact with the sealing compound (which will dissolve and drop into the acetone and contaminate it.)
