They are "worth" about that, $125-$150 as full retail. They would never bring that in a true auction format but if you had one as a buy it now on ebay at $99 I bet you sell it. I have sold some beautiful vintage ones in the 150 range but a later in life 3X5 is probably realistic at around 100 if you want to move it, higher than that it will probably sit for a while.
