2 small medieval coins with a crown, possible Hungarian [Risolto]

Hello experts!

Got a bunch of coins, mostly were hungarian, but those two I cannot ID, the first and small one I tried some eletrolysis, now at least I can see something.

I browsed the entire Hungary catalog of Numista, no match for any of them.

First one (redish):
Diameter: 11mm
Weight 0.5g

Second one (greenish):
Diameter: 14-15mm
Weight: 0.7g

There are a crown for sure in both of them.

Any thoughts?

Hello!
I think the bigger, green one is a Zsigmond quarting. These coins are made in really bad quality, so mostly you can’t figure out the mintmark ( I have 6, and just on 3 I can see the mintmark)

Thank you very much for your answer

After searching several hours, I found a match in this catalog

Seems from V. László, two different types, I just added to the catalog since the coin is not in the numista database.

Thank you again!
