I inherated a set of cast iron garden seats armchairs with lyre-back design from my 95 year grandmother a few years ago old. They have scrolled and floral elements, as well as a few layers of paint with lots of patina. Size approximately: 32″ high, 20.5″ wide, 22″ deep, seat height 16″, depth 17″. The chair on the right side of photo has no damage (good condition); however, the one on the right side of photo has a piece about 1-1/2″ broken out of it (about 3″ up from seat on back, off to right of large lyre, next to arm). Grandma had them for approximately 60 years (I don’t know where she acquired them or how old they area). I would like to sell them but I don’t know what they are worth or where to list them for sale (perhaps an online auction house; something more professional/specialized than ebay or craigs list). Can anyone provide me with insight or point me in the right direction.
