Scott Catalogue 2G Numbers?

[youpiao]

In this thread on the StampCommunity forum, a member lists all the stamps printed by the US and other countries using the Stickney Rotary press.

This is one paragraph from the post:
Coil stamps line perforated gauge 10 horizontal: 448-450, 486-489, 604-606, 722, 848-851, C37, C41, (RF23, RF27, 2G9-2G10)

My question is, what are 2G9 and 2G10? I’ve searched through my Scott Specialized US, and can’t find anything with a 2G prefix.

2G prefix is for food stamps.

Stickney was also used on cotton order stamps, which have the 1G prefix.

I'm going to guess your next question

They aren't listed in any of the Scott catalogs -- you have to go to Springer.
