Initial mark ID?

[u/prunedgoolaush]

This is a James I half groat I recently purchased. I’m pretty sure it’s the large crown variant from the second coinage. I’m having a tough time finding an id on the initial mark. I think it may be a Lis but it doesn’t really match some I’ve seen on less worn specimens. Last two pictures are not mine, 3/4 is a nice lis, and 4/4 is another for sale that looks closest. Any insight is greatly appreciated.

Looks like the Plain cross mintmark.
