I am having a tough time narrowing down this old coin from Vietnam - the holder it came to me in says Annam, which I now know was the old western word for Vietnam. I am able to translate every character but the first - " ? Vinh Thong Bao" - and it is those first two characters that seem to help most with identification. But, as I understand it, even with the translation, there were many uncatalogued private issues of coins like this so I may be out of luck anyway. At this point, I'd be satisfied enough with help dating it. If anyone has something to share, it would be - as usual - much appreciated.
