Is there anything you collect that you feel like you're the only one doing it? [View all]

For me it's my collection of letter openers.
Mostly mid 20th century of all kinds of styles, materials
some branded
From back when the daily mail was everything and the main communication or business tool for many

I also have a collection of Old Time Radio premium badges and rings
the send away stuff from the 1930s
sad to say I feel old just looking at it all and I've noticed the markets for them are dying off, literally.
