The value really depends on who is in the marketplace seeking an example from this bank.
The closest sold record I've seen is from a Lyn Knight sale in 2012 where a Series 1902 $5 Plain Back sold for $2,070.
Yours is in the Very Good to Fine range in my opinion. Collectors of nationals understand that these notes saw circulation and often show signs of it.
It is my opinion ONLY this is worth at least $1000. Could it sell for more? Of course.
