Cost of tokens in a pachi parlor?

[JReed357]

I was contemplating the other day on how much a token would actually be worth if I was playing in a parlour... Lets say I had £100 (17951 Yen) to spend, how many tokens would I get? I thought it would be quite an interesting conversation and if anyone knows the answers that would be awesome!

897 tokens with 11 yen left over (20 yen a piece) for regular Pachislot, there are also 5 and 10 yen machines, but the redemption value is less.

Those are the 'loan' rates, redemption values are approximately half.
