It's definitely 5 rupees Daryl, KM# 19 & KM# 19a.
KM# 19 is only listed as 1972 whereas KM# 19a is listed as 1972 and 1974 and both are silver;
but what I want to know is there a KM# 19 dated 1974 ?
Tony, I have checked my Krause DVD, Numismaster and NGC and they all list the same info that you have already found although, interestingly, they all seem to show an image of a 1974 Proof next to their listing for KM#19. I think that is probably just an error on the part of Krause which has been replicated by the others. What was your reason for asking - do you have a '74 that you think might be Cu-Ni?
Just because you can't see it ... doesn't mean it isn't there - Anon.
Hi Rick cheers for your reply, I have just ordered a set from 1974 up to 5 rupee so was wondering if it's silver or cupro especially as the set was only £7. will let you know when it arrives as I was a little suspect at all the coins being from 1974.
