How much could i sell my drums for...?

I have a Metallic Cherry Red Remo Enforcer 5 piece drum set with a replaced snare that is a Sound Percussion 4" Piccolo. I want to sell them, they are in good condition, jus need new heads. Its a 14" snare 13", 14", & 16" toms, and a 22" bass...i was wondering how much i should sell them for... I was thinking about $500... Is that too much??
