Value of a Mersman 8182 Coffee Table?

Truthfully - no one can really even guess as there are so many styles of Mersman coffee tables and the numbers on the bottom do not really help as there is no "list" anywhere that I have ever found that shows numbers as they relate to value or even age. That is why most Mersman furniture will be shown as "mid-century".

Some styles are more popular than others but any of these tables are generally slow movers on auction sites. Shipping is always costly and very difficult so most of the time sellers will list there tables as "pick-up-only" which limits the sale to their area and that may not get very many interested parties (no matter the price of the item).
If you are interested in selling I would suggest you might list on your local Craigslist or any local auction site. If your table is in good condition then I would suggest you start your listing price at $150 and show lots of photos. If you get no response then you can lower it as you see fit.
I will say that it seems large table are sometimes more difficult to sell as they take a lot of room that most be do not have plenty of.
