I want give some advice as an old time collector. (1) When I got interested in this hobby, I thought. Why am I interested? Well, the answer is, I like quality (anything) and Griswold answered that. (2) I like cooking, so I decided to collect only cooking related items. (3) I learned enough to know that I couldn't collect it all. I decided that I would only collect Griswold cooking related items. (3) I knew enough about collections that quality is everything. (I had dabbled in coins a bit)
With all that said, that was over 40 years ago. To this day I don't anything but Griswold cooking related items. I don't own a piece that is cracked, pitted, or warped. If it's not very near museum quality, I am not interested. I don't have the biggest collection, by far, (only about 300 pieces) but what I have I'm proud of and glad to display it. Even my "user" pieces are really nice.
I don't think I can give any better advice to the new collector. I see questions all the time about what a damaged piece is worth. In my opinion, nothing.
I'm not here to say, do it my way. That is up to you.
