How can you date and value a Bank of England One Pound Note Chief Cashier J B Page S89M 832333 circulated condition a little tattered?

Answer 1

A Bank of England 1971 One Pound note (Series C - green)(Chief Cashier J.B. Page - serial S89M), uncirculated and in absolute mint condition could fetch anything up to £25 GBP. If it has been circulated but still in good condition, it might fetch anything from £6 to £10 GBP.

A reputable coin dealer will be able to give a more accurate valuation.

A combination of the Chief Cashier and the serial number can pin the note down to a year or two.
