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.

The gold casing!? 

Uhhh, I'll buy that game off you? :)
