Bonus collect could be for minimum value (1k), even variable jackpots start out at some not-insignificant base value.

Bonus also, as noted, can still be collected via drain if not collected on PF during play.

In many older games the bonus collect was the biggest shot on the playfield, and could be considered a 'jackpot' per se when you collect it.

Many newer games feature both one or more jackpots (usually although not always in MB) as well as a bonus collect:
- JM has bonus collect via keypad, and jackpots in MB
- DM has bonus collect via Computer award, jackpots during MB, and a demolition jackpot collected in single ball play
- TZ had a bonus collect via Camera, a regular jackpot in MB, and a jackpot in Powerball Mania that goes to bonus, and can then be collected via bonus collect!

'Jackpot' as a term wasn't used until High Speed I think, though many games before that had large shots you could collect (Mega score on Road Kings for instance)

I would think that if the game doesn't say "jackpot" in some form then it's not technically a jackpot...

You don't collect it when you drain, so why would it be a bonus?

I haven't seen it anywhere

Regular bonus is built in numerous ways, including modes and power ball mania. jackpot is built by hitting standups during MB.

Jokerz, 1988, has collect bonus and jackpot.

It has a 'target bonus', which is not a regular bonus the same way that the 'bonus' in abra ca dabra (scored on every lit drop target hit) is not a normal bonus.

I think the jackpot is raised by something like the pop bumpers.

Jackpot is variable (shared between players), increased via upper playfield lanes. Collected by shooting ramp four times during MB.

Bonus is advanced via lanes, rollovers, etc as normal. It's collected by completing the upper playfield lanes.

Many games with a bonus collect don't reset it. Jokerz, TZ, Bow and Arrow (and almost all bally ems). I like to think of this as 'score bonus' not 'collect' since they seem very different in how they play, but everything seems to call it collect either way.

Bow and Arrow, Old Chicago, Nip-It, Delta Queen to name a few. I don't actually know of any Bally's with collect-and-reset, but my knowledge isn't that big either
