Here is a fun quiz good for a holiday...not too difficult. I got 18 correct out of 20. https://www.funtrivia.com/playquiz/quiz98681b4e5c0.html
18/20, should have been 19/20 (bonehead mistake). Fun quiz! If not for reading CoinTalk endlessly I would have scored 0/20 .
1/20. But I think I found a mistake at question # 18. The answer should be Roman Provincial coins, no? So I’m 2/20.
19/20. I missed the weight of an aureus which I know in grams but did not convert properly. Considering I will probably never own an aureus, all is well.
17/20. I missed the aureus weight too - if I owned one I might've guessed better, maybe. Then there is that very early Roman Republican stuff...oops.
