Help To Identify Revenue Stamp Paper On Bank Check

Can someone please assist me with identifying the Specialized Scott Number for the Revenue Stamp on this bank check? It was issued by the Nassau National Bank for the Brooklyn,Flatbush and Coney Island Railway Company.( Boroughs of NYC) I am aware this company was incorporated in 1869. This is an unused bank note with faults.
The stamp appears to be liberty 2 cents. Is this a common design or scarce?
Any information would be appreciated. Thank you

Lioness, I must be going blind because I do not see the stamp?

Hi

That is Scott RN-G1, revenue stamped paper.

It has a catalog value of $6 unused and $4 used.

Thank you, Jim and Peter for your responses. Appreciate it!

The stamp is common but for this particular RR, probably not as common.

BTW, at the time of this check Brooklyn was a city unto itself, and Flatbush and Coney Island were separate from it. Brooklyn became part of NYC in 1898 (whether it wanted to or not).

Peter, the "stamp" is the printed orange diamond in the center.

Not listed in Castenholz, which isn't necessarily an indicator of scarcity. I have quite a few RNs not listed in Castenholz that were acquired cheaply.

The Castenholz books are just the top of the iceberg. "Unlisted" means very little, but is touted by many sellers.

I acquired it cheaply from an Antique paper and Map collector. He had large collection of paper in boxes which included various stamps on envelopes from different countries. He sells in NYC and comes to this area on his route. The boxes were disorganized and did not have the time to look through all of it. He had a trove of paper materials including gorgeous maps from 1700's to the turn of the century. Many were in very fine condition. I can tell the maps are genuine, but delicate. Kind of upsetting how they were not preserved so properly, including individuals should never touch without gloves. He claimed that he bought railroad materials in NYC years ago and this revenue stamp paper found loosely in the box. I will again return to see him once more and view his collection more carefully in the future.
