“It’s quite possible that British (shillings/pence) currency was used interchangably with the local (shillings/cents) currency.
It’s also possible that there was some confusion in the printing of these forms (they may well have been printed in Mother England).”
Sorry “Kenya used pennies” = Kenya used cents (before 1966).
It’s also possible that there was some confusion in the printing of these forms (they may well have been printed in Mother England).”
Yes, as I've said before there are just too many possibilities to come to any safe conclusion. One has to get a another certificate to compare with.
