CARLVS REX FR (circular legend around a cross surrounded by a circle made up of dots, a cross between FR and CARLVS).

Coin seen on: http://www.coincommunity.com, link to the page showing the coin: https://www.coincommunity.com/forum/topic.asp?TOPIC_ID=297965. 

Monogram Karolus:

(1)  Without letter A in the diamond on the middle.

Despite the state of the coin, the monogram seems to be (1). The only difference with type 1 is the letter S tilted on the reverse.

Seems never to have gone on sale.
