Thank you for posting this @FVRIVS RVFVS. What a lovely BIG coin. I agree with @Bob L, that even with the verdigris it is pretty.
To see an even more impressive one via the link, was an eye opener for me. Imagine walking around with a few of those in your pocket!

Thank you also for the link on the other page @echizento. It is a fascinating read. I had often wondered what the purpose of the circular divot in some of these coins was for, and the article explains a lot more too.
