3 3/4 for me. But I wouldn't say I'm a collector so much as I still have all my G.I. Joes and have no intention of selling them (or displaying, I guess, for that matter). Yes, they will likely be played with by my children when they get older (too young right now).
Anyway, best book I've found thusfar on the topic is from Mark Bellomo. It's a good read and great reference. It's the Ultimate Guide to GI Joe (1982 - 1994).
I've heard that GI Joes can be worth tons of money, is this true or false?
It depends, like anything in the collector market. Things like condition, packaging, accessories, and rarity of the piece all contribute to demand, demand is what drives the market. The best thing you can do is look up what you have on eBay. this should give you an idea of what you have is worth.

I collect Joes. I more so collect the 25th/ME stuff and some of the new ROC/POC stuff. I have some vintage vehicles and bases only if they will fit the modern style Joes.
