In the recent (7/15/10) RCNA auction, G Bell offered lot 1311 described as:
"CH 535-10-04-04. Good Condition, hole is present, foxing on edges. Charlton Catalogue states "notes not confirmed" well we're confirming with this possibly unique note. Expect plenty of interest in this note. S/N 2541"
The Charlton catalogue lists 4 varieties for the $3 Niagara Suspension Bank notes. See the below.

This note certainly seems to be a discovery note. However, I am having trouble deciding whether it is of the Second variety, in between variety 1 and 2, or whether it is a counterfeit of the 4th variety. See my arguments below:
