Mid Century Desk

 I have this desk and I think it's a mid century desk based on a very similar item i've seen online http://www.metroretrofurniture.com/cgi-bin/store.pl?item=9973&cameFrom=322. It's almost the exact same item, but the legs on my desk are metal, but painted over and not chrome. It's in fair condition.. drawers are in great condition and overall desk is also great.. doesnt have any major scratches or dings.. but just wear from age. want to sell it and want to know how much I can sell it for. The only distinguishing marks are Kronaflex rollers and from googling them, looks like the company that made them delisted that trademark in the 70s. It's mostly wood veneer with metal legs. It weighs a ton and I'm not sure why.. the desk is very sturdy and I think the weight is probably the table top which is super thick and I dont know what it's made of.
