Constantius II as Caesar - Fantasy Piece?

[KostasAlexander]

A friend sent me a picture of this coin that he got in a big group lot and asked if I could ID it for him.

Dug through Ferrando & Lech's website and couldn't find anything. Reverse legend CONSTANTIVS CAESAR.

Anyone have any ideas?

it's copying a silver siliqua from Constantinople

"Lipanoff Studio" has made lots of this type in "silver"
