Almost all guns which sell on GunBroker seem to start out low and have no reserve. Others, listed at retail prices never seem to get sold. But its hard for many to just list a gun at a dollar with no reserve and hope it sells for what you think it should. Low grade doubles are very much a hit or miss thing. Shooters can be found for reasonable prices unless you are the seller in which case they all go for too little.
Ive sold about a hundred guns with Gunrunner.com and been both happy and dismayed at prices sometimes. But over all they have done well and half of selling right is buying right. Or just buying years ago when prices seemed lower. As an investment guns suck. As toys you get to enjoy they have been fine.
Lately Ive been buying more pump guns than doubles. There are a fair number of different pump gun designs, many long forgotten, that are interesting to compare how they evolved and I get to shoot most of them as a extra benefit.
