Any wrestling fan has some pieces of memorabilia, but only legit fans have a lot of those items.
Here's a list of wrestling memorabilia you should have if you are a legit wrestling fan.
If you have at least one item listed you're a casual wrestling fan.
If you have all but the last three, you are a legit wrestling fan.
If you have absolutely all of them, you are a hardcore fan.
And if you have collections of all items, you work for a wrestling company (or know someone that does).
