[Woodcarver] OLD Tool value?

[RICHARD L ROMBOLD]

This may have been talk about before, But I don't remember it (that happens a lot lately). 
How do you put a price on old caving tools, some that are 40- 50 years old, and sometimes older? I am often asked to appraise some tools for a estate. Mostly they are just users, not antiques. You put the price to low and they think you trying to rip them off, to high and they wouldn't sell. 
If someone has a price list from the 1940/1950's/ 1960's, that would help.
Thanks.
