When showing your Collections, Do You just leave out the Lower End Pieces?

[MILGAUSS88]

I have quite a few vintage Omega Seamasters, my experience has been that by the time your friend has seen the 5th box of watches, that they have gotten the idea and are getting a little bored.
I have shown my collection to four people that I thought would appreciate them, only one had an interest at looking at them all, and I think he had more interest in the monetary value.
