Maravedis ? [Resolvido]

Hi all!
I am trying to identify this Maravedis.
I think that's copper, 6.2 g of weight, 28.6 mm of diameter, 2.0 mm thick.


On the reverse I can clearly see a rampant lion in a shield, facing left and there is what looks like a "1" on the right of the shield.

On the obverse there is what looks like a castle in a shield and, on the top left, maybe some lettering.


I am assuming they are from the XVII century. Can we go any further with the denomination and the king?
Thanks
B.

8 maravedis of Felipe III or Felipe IV

I did (or at least tryed) a very similar Id this week. For you I have almost the same coment for you but with some more hints since your coin has a few less detail.

I think its needs to be a 8 Maravedies coin from Felipe III because:

- its kind of castle and lion inside a "shield".
- Its kind of castle itself.
- Weights are around 6gr... ok for that ID

Coins from Felipe II, as far as I recall, do not have that kind of castle; coins from Felipe IV mostly changed the castle for his bust (father and son of Felipe III). I may be wrong but at least you have a few hints to keep trying

Edit: I just saw the coment of Zegeri, the refree for Spain, always listen him!

I was totally wrong with Felipe IV, the lion was changed

Awesome! Thank you both for the help and the informative comments!
