Blaster Master CIB MINTY

All are 7 day no reserve auctions ending next Sunday evening (1/21/18).

I mean you can sell your stuff for whatever price you like but $150 open and a $500 BIN? New sealed ones barely sell for your opening bid on this used copy. In the condition you have there they sell fro $20 to $60 at best in case you want a rough figure for when you inevitably relist this:

Most of those are a little nicer than your copy but you get the idea what it sells for even in actual mint condition, not just very good condition.
