It goes like this.

Prod round 1 - 1981 - White cab full / size - the most valuable.
Prod round 2 - 1982 - Special Edition cab - worth about 60% of the original in $$$.
Prod round 3 - 1984 - Bally/Midway full / size - green cab - worth about 70% of the original in $$$.

This pin is famous for wear near the drop target area. Beware.
Probably the largest range of cost, for any classic pin ever.

SE cabs can be had for as little as $800 with some imperfections.
The original white cab in mint cond. and with a clear coated playfield can fetch up to $3,000 or more.

If you like the pin and find any copy in good condition, $1,400 is average for SE, $1,800-$2,200 common for the original white cab.

The 3rd version, I believe, has decals on the sides instead of the painted cabinet.
That's a big cheapo way out, and many classics enthusiasts do not like it.
