Personally, I prefer 18th century Mysore coins.

Back then, any Mysore coins which bore a date used a calendar virtually unique to that state: the "Anno Mohammed" calendar, where year 1 is the year of Mohammed's birth (as opposed to the "normal" Islamic Year 1 dating from the Hejira, which happened when Mohammed was an adult).

Collecting coins which use different, unusual and obscure calendars and dating systems is a theme I'm developing, so I was pleased to pick this one up. It's not as pretty as yours, EK:

Mysore, copper paisa dated AM 1217 (=1787 AD). The date is written in Hyderabad numerals and is read in the opposite direction to normal Islamic or Western dates.

It's from the Philippines, back when it was an American colony.

Quite popular with American collectors, as they're the only "American colony" as such to issue coins back then.

My latest Roman acquisition, from my local dealer. A common enough type, but much better condition than most of my collection.

Obverse: Emperor Caracalla, ANTONINVS PIVS AVG BRIT

Reverse: Liberty standing, holding the pileus (liberty cap) out in front of her while leaning on her staff. PM TRP XVI COS IIII PP. The reverse legend gives sufficient detail to enable this coin to be accurately dated to 213 AD.

It may seem a bit incongruous to us today, particularly to Americans, to see Lady Liberty and one of your more despotic Roman Emperors sharing the same coin. But remember, Rome was still theoretically a Republic.

Listed in Sear (millennium edition) as #6830, apparently in RIC as #209a.

My dad gave me two Fiji coins, a 10¢ and a 20¢, he found in the church offering plate yesterday. We occasionally see Fiji coins in change down here, but two in one day hasn't happened before.
