I'd call it a good price.  These are the downright prettiest ones made.  
People
who know them like them a lot (that would be me).  Several are on eBay 
right now,
listed with starting bids from one at $6.99 to over $40.

Yours is quite early.  Easily dated, as Goodell Brothers became 
Goodell-Pratt in 1899.
There's a great page on these (and other Goodell Bros & Goodell-Pratt 
tools) at:

My first one was a #22 I picked up for a ridiculously cheap price.  The 
other is
like yours I picked up later from eBay.
