Singer Sewing Machine Model 639

Great looking machine and sewing table. Unfortunately, these aren't worth much and can often be found for $100-$200 or less at flea markets, swap meets, and yard sales. Some very very old antique sewing machines can fetch more money. Your Singer Touch & Sew 639 is from the late 1960's.

I agree with Joseph, comparable machines often sell at Goodwill/Charity shops for under $100.00.
