Oldest and newest...

Sylvestius

What's the oldest and newest world coin [minted with circulation in mind] in your collection? (by newest i mean a coin that is actually in your collection, not in your pocket for spending when the chance arises), patterns, proofs, non circulating bullion and commems are excluded. Only coins minted for active circulation are in the spotlight this round.

For me my oldest would be my Stephen penny minted sometime between 1136-1145, (i nearly bought a Canute one the other day which would have out done it by 100+ years but thought better of it when the Mary one came up).

My newest would have to be my 1864 gothic florin. (I would have said the 1937 Edward VIII Modern pattern crown, but since it's a pattern it's not a real coin and thus exempt).

My oldest would be a Greek silver thingie and the newest would be a 1901 Penny (as proofs and commems are excluded).

I excluded proofs and commems cos i though it might give a wider date range, if not then everyone's most recent coin is very likely to fall within the last 10 or 20 years.
