Turning Lead into Gold?

I've been collecting miniatures since the year dot (well its probably only since 1986 or 88 I cant remember exactly), and basically my collection been growing every month since then. Some of it is pretty rubbish, and some of it is pretty decent, but small bits of it are pure gold. I have, for example, this Limited Edition figure in my collection:

LE 4 Space Marine Captain 1991

Still in blister, and looking good after 20 years of storage. Here he is on Solegends.  I wonder how much he would get on ebay now? Any Offers? (Im not selling!)

[UPDATE]
It looks like someone on ebay has been thinking the exact same thing as me, with regards to this figure! http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170699113746#ht_500wt_1361 Hopefully I'll soon get an answer as to how much this figure is worth!

[UPDATE #2]
Well I have my answer. The final price including postage was £48.56! Thats a nice profit for a single figure - But Im still not tempted to sell! (well not yet anyway!)
