$ 1,600 is a very attractive price on this O/U Cynergy ...but a collectors item, no I don't think so ( not even if you left it unfired in the box ..).
In my opinion, Browning just produces too many guns and too many models for it to have any "collectors" value...but I do think it will go up in value at a purchase price of only $1,600.
For what its worth - I showed my 18 yr old grandson the photo last nite - and he thought it looked pretty cool....
