Title says it all. I always thought I'd keep every pin I ever bought, but now have the excruciating need to make room for something new, so I was wondering what the largest collection is of someone who still has EVERY pin they've ever bought? If you've got them out on loan or on route, that still counts, but they must still belong to you and you can't EVER have sold or traded a pin in any way. Very curious to see whether the high mark will very high or fairly low.
