Some US BOBs I've come across

[gbauer8946]

I think I've seen the green Documentary stamp before but can't say I've seen any of the others:



Does anyone else have any or know what they are?

The black ones are 1945 U.S. Postal Note stamps (Scott PN5 and PN8).

The red ones with black overprints are 1918-1922 (sans serif front) or 1920 (serif font) U.S. Stock Transfer stamps (Scott "RD" numbers).

The green one with black overprint is a 1918-1922 U.S. Stock Transfer stamp (Scott (RD30).

The orange one ... I have no idea. Can't see any details in the stamp.

Using my sleuthing skill, I would say the first two are postal notes and the last five are stock transfer stamps.
The orange one I'm having trouble with, since I can't read the writing, except for the 2 cents part. smiley-face-whistle-2

I don't know why the image wouldn't zoom. Here's the orange one zoomed. It looks like it was issued by Massachusetts. Are those typically in the Scott catalog?

[Craig]

No, state revenues aren't in Scott. I don't have a state revenue catalog, unfortunately.

Thanks Craig. If those things are going for $4.99 on e-bay then I got a really good deal on it for a quarter
