On the reverse, it appears to say [CIV]ITAS RENGHT, which would refer to a city called "RENGHT" (???)
The obverse appears to refer to a FERDINAND, which isn't exacly a name I'd expect to see on something Roman.
The 1921 "peace" dollar is relatively scarce, but the 1921 "morgan" dollar on the other hand is by far the most common and readily available US silver dollar.
Personally, I prefer that things be spread out. That way a major accident/incident wouldn't be so bad.
The loss of the most intact Spinosaurus fossil during WWII is an example that stands out to me.
Other examples of loss of artifacts and items/sites of cultural importance include Afghanistan (over the 1990s and early 2000s, many non-Islamic sites were destroyed) and China (mid-1960s)
The '80s £1 are neat, but the regular £1 with the ship and the 20p with the lighthouse are quite neat to me.
All I've got to show for the measly £200 or so of coin that I've handled over the past year is a 2004 Gibraltar pound.
re: Hong Kong - there was also a 10-sided $5 coin in the mid-1970s. It was withdrawn and replaced with the slightly smaller but thicker $5 coin used today.
I have a $2 coin in a official-looking cardboard sleeve so I believe that it probably wasn't meant to circulate.
The Bahamas silver 50c I have encountered in circulated grades on several occassions.
St. Helena - never seen those before! I better put the 50p on my watch list
Falklands - only seen the 1p and 20p - very nice to see the rest of the set.
