George Paul's collection is one of the finest I know of, and certainly one of the most beautifully presented. I envy him having so much room!
I have never considered collecting to be competitive. We all have our interests and we all enjoy our treasures. I've never begrudged anyone for finding machines that I might have wished to own. There's plenty to go around.
I am completely appalled by a (relatively) recent trend in coin collecting, which is flat-out competition. One of the third-party grading services set up a "Registry Set" competition where collectors can post about their specific collection focus, and compete against other collectors in the same field -- with the third party grading service setting the standard and choosing the 'winner.' I find this revolting, but it has been hugely lucrative to coin dealers and auctioneers as people spend incredible amounts of money for fundamentally common coins because they have a very high grade. A coin worth $20 in superb "MS-65" condition might sell for $10,000 if if happens to be put in a "slab" with a label calling it "MS-69." There's no real basis for such prices, other than a handful of "registry set" collectors all wanting the best of the best to "win" their niche. I have to give begrudging respect for utterly brilliant marketing by coin dealers and graders, but collecting is not a sport and competitive collecting is simply wrong in my opinion.
Bottom line: I collect for me. If others like what I have, great. But I don't need anyone's validation. I buy what I like, and I appreciate them.
Since I posted photos a few years ago I have downsized quite a lot. But my house is still bursting at the seams. I seriously, really, don't understand how I could have sold 25 machines and still have absolutely no room.
