Circulated Coin

what is the world’s largest circulated coin?

I would like to know what is the worlds largest coin that was in circulated, ( No tokens or commemoratives).

It would take a long time to look for it but I would guess that it would have to be a double or triple Thaler from one of the German States. I have books that go back to 1601 and up to 2009 but that covers unfortunately a lot of pages and a lot of time to check. There are some very large ancient coins also but it is questionable if they actually circulated as money. Sorry this is the best I can do here. As for the so-called stone coins of Yap, yes they are huge but can not be moved from one place to another and are not considered real coins anyway. They are considered primative money.
