where would you determine the value of your games?

Look up prices on ebay.

Just tried that but cannot find any results, not sure what words to search for for a combined Mario, racing and Tetris game.

If you're serious, you'll be thousands of dollars better off if you sold that game

Why, what makes it rare, the gold casing?  LoZ NES has one too.

I'd guess you already know and it's a joke, but for the heck of it... because there are only 26 in existence... that is assuming it's not a reproduction cart.

The Nintendo Power version of Nintendo World Championship ironically being worth more then the version given out to the participants due to it's relative rarity.

As far as I know it's the most valuable game in gaming.

Outside maybe the rarest "swordquest" series on Atari.
