For me it is sometimes confusing having conflicting info found in KM and Numista. Which is right? The 1/4 Anna coin dated AH1315 is found in print to be made of copper, bronze or brass. I'm curious if one of these might be a mistake? Does the genuine coin come in copper & brass? Or maybe copper & bronze? Or maybe bronze & brass? Anyone know for certain?
NGC World Coin Values reveals all Muscat and Oman 1/4 Annas to be made of copper. ?Perhaps patterns or trials could have been made in other than copper?
I have been looking for both types of the M&O square 20 Baisa coins, for more than 30 years.
I believe I have the Worlds second largest collection of 80 different machine struck square coins, minted strictly for large scale circulation. As far as I can tell, a guy in Denmark has a bigger collection square coins than mine.
Almost all of them have a collector value of less than a couple of dollars or so, (which is why maybe very few people have bothered to build such a collection). All of them are in base metals
