There's obviously no "set" price for anything sold like this. But factors that can affect price include:
- How much the seller thinks it's worth (it could be "that old machine in the back" or it could have been the centerpiece of years of parties)
- The game itself (there are some games that aren't great, and there's some classics)
- How common they are in your area (some towns have a lot of collectors, which drives the price up. other areas have surpluses of arcade games, such as if an arcade just went out of business etc)
- How long it's been for sale (a guy trying to sell an arcade game on Craigslist for a long time will usually drop the price)
- How motivated the seller is (short on cash, need to pay the electric bill before they shut it off, so scrounging up cash ASAP)
The Golden Tee games tend to be higher in value because they're popular. Bars, bowling alleys, and your local man-cave like having a Golden Tee around, because it gets played and makes money.
