I think this is the 5th or 6th post on this today However, yours is the first I have commented on I found 425....Did I say 425? I meant 424 gold coins...
I like this sentence: " . . .the 425 24-carat pure gold coins would have been a significant amount of money at the time." Today, of course, that's just chump change.
A small fortune at the time, indeed. Enough to buy a nice house in al-Fustat, the capital of Egypt. (Now part of Cairo's old city)
