Do you remember the (mercifully brief!) 'real prizes' phase that AWPs went through?
It was towards the arse-end of the £6 jackpot era and they were scrabbling around a bit for a new hook, so some bright spark came up with the idea of having an 'extra jackpot' whereby the machine could award a real physical prize (the value of which could not exceed £6), but was treated as a £6 win the same as any other, so fully accounted for in the RTP.
As such we ended up with a rash of machines that paid out dreadful watches, cufflinks, lighters and all sorts of other random horrible shit that no one in their right mind would ever want to do anything other than set fire to (which they could theoretically do if any of the lighters ever worked for more than about 5 minutes).
Where the machines didn't pay out an actual prize themselves, they would instead pay out a 'super token', which you had to take to the cashier's desk in the arcade or to the bar in a pub, and they'd offer up a box of shit you had to choose your prizes out of.
I remember a Bullseye in a pub going on a streak entirely in super tokens, I ended up choosing 6 or 7 rubbish prizes out of the box of tat behind the bar, and then hawking it around the pub for £4-£5 per item to try and get some of my money back
