You might be richer than you realize because Out of Production (OOP) and Rare Games Workshop Warhammer models go for a princely sum !
You might find it's worth hanging onto those cherished minis for a few years because some of the rarer ones are fetching big money on eBay. If you have any new in the box (NIB) metal minis from an abandoned army building project take a look at the eBay completed listing to get an idea what they're worth. Or better still, keep them in your loft for 20 years until Fantasy Battle becomes the next big thing in China and then see how many Yuan you can get for them. I wouldn't mind betting that they will go up in price far more than if you left the cash in the bank !
Anyway, here's an example of an Empire unit of Teutogen Guard that someone recently bought through eBay from a link on this very blog. See what I mean ?!
