To determine an antique hand saw's value, first inspect it for damage. Dents, chips and rust can all affect the tool's value. Next, identify the brand name and product line. Top of the line antique tools that feature quality components in good condition are of the most interest to collectors.
After identifying the brand, try to determine the saw's rarity. Some older tools are very rare, especially when in good condition. Original paperwork and packaging can also increase the value.
Antique tool dealers such as FineTools.com and VintageSaws.com offer appraisal services for a fee.
