Spanish silver Love Token?

[Aureus]

Found this one yesterday. It's a 1783 Carolus III of Spain half real with what appears to be letters "A.H." inscribed on it. Underneath the letters it seems to have the date 1818, also engraved. Not sure if it's a Love token or something else.

Thanks for the comments.

Here's another thread about engraved coins:

This was one of the most interesting threads I ever worked on...
