You'll find it illustrated on page 376 and priced on page 377 of the Charlton Standard Catalogue of Canadian Bank Notes, 5th Edition.
(the catalogue to which you referred lists PEI treasury notes, not Bank of PEI notes)
It's quite a pricey note, with either variety valued at $1,000 up.
I'd be glad to have the details such as sheet number, signatures, overprint if any, etc. for the register of rare Bank of PEI notes.
