I don't like to sell. I've sold a few lots of dirty Heatons in order to let some out for other collectors but money has a way of turning into nothing real fast. A bill paid for one month, or a marble I can enjoy for years... I'll take the marble unless things get real tight. I do trade now and then, and I try to make the recipient of the trade come out on top. I can get rid of a few like that. Selling them is hard but giving them to someone who really is enthusiastic is easier.
As far as displaying, I don't have many on display. Never got the time to find or build display cabinets. It would be an undertaking. One day maybe, but life is so busy. Got some jars and cullet out, but I can bring out and show things easily.
