But not very widely and not for very long. The point I'm getting at is that, if we're going to exclude the US-Philippine issues, we have to first establish what a "US coin" is.
A fascinating discussion throughout. One thing that strikes me is the number of people (100% of them Americans I assume) that consider them as US coins! If they were struck (and to me it doesn't matter where or by whom) for circulation in the Philippines only then they are Philippino coins, which is where you will find them listed in Krause. Trade dollars are different because they were struck for use within a sphere of influence that spanned many countries so yes I would class them as US coinage. The same would apply to trade dollars struck by Great Britain as being British. But at the end of the day it is your collection so you class them as you want. (And as it's the end of the day...time for a beer.)
But the additional fact to consider is that at the time the Philippines were a territory of the United States and therefore part of our country at the time they were minted/used. So although the coins were for circulation in the Philippines only... the Phillipines were actually the United States at the time. Accordingly, they were intended to circulate in the United States
And here we get back into the colonial question. The United States militarily occupied the country with no regard for the wishes of the people. If one was to apply your rules to, say, the British Empire then most of the world's coinage of the 19th and half of the 20th centuries should be classified under Great Britain. Same applies to French, Dutch, Spanish, Portugese, German, Japanese occupations.
Point taken CheetahCats. Any further opinions I have on this subject will be despatched (dispatched) to the knacker's yard.
I have one, and I don't list it as an American coin. Technically, I probably should, but I don't, and it's my collection so who's going to stop me? I also list each name change as a seperate country...IE, Malaya and Malaysia are listed as two seperate places, count as two different countries on my country chart yet are really the same place with just a different style of rulership.
