I find both suspicious, the first should be Valladolid, but the privy mark, while similar does not look right to me. The second looks better but I don't like how the assayer's mark looks. This doesn't mean the are fake, just that I am suspicious.
Welcome to the forum. I specialize in later Mexican 8R counterfeit varieties and other colonial issue counterfeits in general, however, I do very little with the copper coins. Good luck finding your answers.
Those coins seems authentic, and I'm a collector of modern ages spanish coppers. Those are known as "cortadillos", because of the form of the planchets. They are not common with all data visible and without restrike.
The Valladolid mintmark seems correct to me.
The cross on the left of the reverse in the Madrid one is not an assayer mark, it is just a cross. There is not assayer marks on spanish copper coins until 1660.
