I don't really collect any Apple or electronic stuff.
But I do have a pretty sizeable (about 1500-2000) trance record collection (I used to be a trance DJ)
Barrell aged Russian Imperial Stouts. This is my only real collectable. I have some beers I intended to age for 10 years or so.
I do buy alot of coffee beans of varying origins and blends,but I wouldn't say I collect them (mainly because coffee has an extremely short shelf life). When doing a tasting session I like to collecf a copy of the trading notes if they've been prepared. I have a monthly coffee subscription and have an electronic and paper copy of the tasting notes and vouchers that I get with it.
I also own 3 trumpets, the trumpet I learnt to play on which appeared in my grandfather's second hand shop about 20 years ago. The trumpet I completed high school with about 10-15 years ago and my current playing horn (I'm on a break atm though.)
