Please help to identify uk coin

Please help to identify uk coin and help with its value. There are some similarities between one penny,  Henry III and HENRY IV, but not the same. thanks!

One side matches this Charles I coin: N#92807

But the other side looks earlier types.

I am wondering if it is a fantasy item, but maybe a UK expert will tell us.

The K seems much more modern than the coin itself.  Makes me doubt the authenticity of the coin.

The surfaces look grainy, and the k might signify that it's a replica.

Though I could not match with any coin. What could be the actual coin.

For a fantasy coin, there is no real coin.

It combines design elements of real coins in a way that was never a real coin.

So … yours appears to combine an obverse of a Tudor penny and the reverse of an earlier type.
