I looked at pricecharting, ebay.com, ebay.ca. Prices vary. I also tried
www.suruga-ya.com but it wasn't much help here.
Price charting had the most data and it doesn't consider condition. The good and the bad are mixed together in the average.
MVS is a lot more work than pricing Nintendo and Sega games.
How do these prices look?
Prices in USD
Galaxy Fight - $190 (Repro Label)
Captain Tomaday - $240 (Holo Label)
Far East of Eden: Kabuki Klash - $225
Andro Dunos - $250 (Repro Label)

Sengoku 3 - $350
Zupapa - $325 (Repro Label)
Rage of the Dragons - $375

All of the carts have the typical and very noticeable scuffs and scratches. And each cart has a shock box and insert that will be include (but that may increase shipping).
