I was going through the loft the other day and came upon a stash of old Transformers. Amongst everything was a character called Overlord with its packaging featuring some neat artwork. Looking things up, Overlord seems to be a character exclusive to the Japanese version of Transformers and this toy was a European release sold in the early 90s. I was thinking about selling this thing along with a few other pieces and then saw some of lofty prices being put up on eBay for Overlord. I don't know now whether I should keep hold of the toy or, if I do sell it, what is the minimum I should expect. Any help?
