You've maybe heard about bootsales (I don't know if they are a worldwide thing or not), if you have, here are some tips next time you go!
1. Look out for vintage stuff: Vintage stuff are things you should look out for, you should check the year on stuff that are vintage, like the At-At (from 1997), the playing cards for star Wars episode 2 (2002) and the clone trooper (2005)
2. Rare cards: you should look out for cards that are rare, like Charizard for pokemon collectors and players that are famous or good (like the Zlatan Ibrahimovic and the Alan shearer).
3. Antiques: you can find antiques such as coins or bullets at bootsales, even rarer antiques would be helmets, army uniform or medals. If they are getting sold for less then £10, then buy them because that is a bargain.
Hope this helps for collected that go to bootsales.
