What I'm trying to say here is there are people out there who would stitch their grandmother up for a few quid. What you have there is a lot of quality stuff, as well as it being worth a few bob. You seem to be a really nice guy but you also seem to be almost addicted to this and I hate to see you lose out because people take advantage of that.
Also, being new to the market you need to be a bit careful because it's never been so inflated. Prices are artificially very high at the moment and no one knows wether it will sustain. That's all.
I will lay it on the line for you regards the other comment. This sort of collecting is guys who drop thousands in a short time and then burn out. Quite a lot of the time they get in too deep too quick and start spending beyond their means. Before you know it they I wouldn't possibly speculate on another persons finances, just hate to see it happen, and we have on more than one occasion. A couple of others have mentioned this already. This is what I meant when I said there is potentially more at stake than just collecting.
Not trying to put a downer on your collecting. It's great to see new members getting into the hobby and you seem to be enjoying it. You also have a sense of humour which is a good thing around these parts. Just remember, it's all been around for 30+ years. It's not going to disappear any time soon.
