Verification On Some Cornados

I've got three Spanish Cornados here that I think I've identified but would like to get some confirmation and see what y'all think. It looks like the image optimizer Pixlr is now only allowing 2 free downloads a day, so I had to get creative. Hopefully it didn't compress these so much that it becomes an issue!

It looks like you can see IOH to the right of the bust. The castle looks most similar to this one:

Still, there are differences in the horizontal and diagonal lines above the doors as well as the circular windows. I do think it's Juan, but I haven't found the exact match.

To the right of the bust, LFO is clear enough, indicating possibly Alfonso XI. There are remnants of what should be an A before the L and running into the crown. This is the closest match I have come across:

The bust looks most similar to Juan II, like this example:

The neck is a little different, though the castle looks pretty close.

On each of these, I suspect I may have the right king, wrong variety.
