Man, what a cool thread. I loved reading what folks collect, especially when it comes to sets.

1. How long have you been collecting pre-war cards?

Exclusively, around 2015

2. What is the approximate largest number of pre-war cards/items you've
ever owned at any one time?

40,000-50,000 cards, I'd guess, though more than half are UK issues that are worth less, including a good bit of non-sports stuff.

3. Approximately how many pre-war cards/items do you currently still own?

Same answer as No. 2

4. What is/are the most significant card(s)/item(s) you currently own?

I don't have crazy expensive individual cards and mostly build sets. Largest individual cards are the usual suspects - Cobb, Wagner, Anson, Matty, WaJo, Young, etc.

5. What complete sets or near complete sets (say 75% or more) do you currently own.

The main ones are below in my signature, but also larger European issues like Ogden Tabs (1,560 cards, about 85% complete), Stollwerck Albums (3,690 cards, somewhere beyond halfway), Felix Potin (1,775 cards/100% complete), and some other nonsense. Some complete baseball game sets, lots of smaller complete uncategorized sets.
