Not sure but years ago I had many more than now. I tried to count a shelf by counting 50 comics then measuring, thinking I'd get a ballpark figure but, as usual, got totally confused and made a mess of it.
So, I suppose, 3 - 4 thousand. Of course, that's way out, because I just turned round and saw all my British and European stuff. We're a wee bit lacking in space here and I sold lots of titles that I didn't want to keep and hadn't read for years. But then, there is a small comic mart in Glasgow on Saturday, so with any luck I'll find some comics to buy there. And I'll also need to buy a present for my wife to make up for bringing more "stuff" into the house.
I am retired but have even less time than when I was working and, on balance, I'd rather read them than count them. This subject tickles my fancy. Curious to see if anyone else comes up with figures.
