How do I determine the value of a game? I cannot seem to find a "guide" for values on Arcade Games. Ultimately I know something is only worth what someone is willing to pay for it. Being new to this hobby, I am buying/selling/trading to get where I want to be and cannot afford a bad investment. I would ike to keep everything I come across but that isn't going to happen so how do I determine which deal is one I shouldn't pass up? I have a line on a couple of games but I don't know how to value them?
Commando, cab rough on bottom edges, everything solid, working, microswitches sometimes stick for joystick $350 or Trade
Shinobi game, power supply went out, everything supposedly working, cab rough (free with purchase of another game)
Rush 2049, cab is in good shape, everything is there, game has an error code, owner suspects a security chip? Project $250
San Francisco Rush, missing screen and wheel. Project $125
World Class Bowling solid condition, game works, owner says game shut off and back on mid play Already made a deal on this one, I pick it up Saturday morning
Thanks!
