Good fortune to whomever bought the game, as it looked to be in very good shape.
For "pincation" (pinball education) and something to understand:
"No pinball title that is proper 'HUO' (or equivalency) ever has had token or pricing decals attached to coin doors at the BLY/WMS factory."
- TBK
These are applied by operators, and are not "options" but often were sometimes included in the token/coin mech packs.
At best case the game was either lightly routed pulled and sold, or in an unlikely case prepped for route and then later resold for private use. It is extremely unlikely a coin door was switched out in its lifetime.
