That was my first Charmkin! I had him, the Jewellery house, and 4 other figures. I gave mine away as a teenager and have had to buy them all back, but non MIB. No idea of price, especially for a MIB but they are hard to find over here anyway. I just need his blue hook thing, and Brown Eyed Susan to get back my childhood collection.
Look forward to seeing if anyone else has info!
