Gio Ponti table and chairs  

@m277hew  Welcome to the Forum.  Your photos must be under 2mb to display.  In general, the best indicator of value is what items actually sell for at auction, not asking prices on online listing sites.  Liveauctioneers.com shows auction results for hundreds of auction houses, if you set up a free account with them.  Many of the larger auction houses also display results on their websites.  A couple of houses that have sold a fair number of Ponti items are Wright (Chicago) and Capitolium Art (Brescia, Italy) .
