Genesis Super Battletank proto

[bb_hood]

Hi.
A friend of mine recently traded for a NES Boulder Dash proto cart. The guy he got it from also has a Genesis Battletank proto and he wants to trade for this as well. I am basically asking what would a genesis battletank prototype cart (or a comparable genesis prototype game) generally be worth?

Any advice would be greatly appreciated, as we both have no idea what either cart is worth or how to price them.

Feel free to move this to the other forum, thanks -Chris

NES protos can range from $80-170 usually for standard released games, and Boulder Dash falls in that category.

Battletank about $50-65

I'm the guy who traded those to you guys.
believe it or not, I actually got both protos at used game stores in the area
