Looks to me its had a long life. Used a lot. Honed a lot but without a lot of spine wear. I nice american razor. But its at the end of its life. Its restorable and useable but not worth much at this end of its life.
We dont put money values on razors but you can look up on eBay for american razors in about the same shape to get an idea. Approximately early 1900s so not real old for a vintage straight razor.

BTW, Welcome to SRP.
