In all seriousness, I will warn you about something. I have found that collecting can run it's course. You can have fun selling then, but it does get tedious and demanding at times. You don't want to leave them to an estate. My collecting became no fun once it got to the level of managing the collection. Taking them out, inventorying them for insurance. I decided to sell them so my wife didn't have to deal with it if something were to happen to me.
I would suggest that owing a smaller number of the highest quality and best examples, the rarest and hardest to come by, is a better plan than collecting in quantity. Collect with a focus and purpose and enjoy it to the fullest. I always got more gratification out of the adventure of discovery and learning than I did by simply owning.
