Need Help Identifiying Spanish Coins

Hello all I've been a bit of a lurker for some months but have enjoyed and learned from the site and now I could use some help. The photos are of a couple of coins I've had for some time but have been unable to fully identify. The silver coin is clearly Spanish but I get stuck from there . The Copper I believe is also Spanish but I not sure. I've spent a good bit of time with Krause's but I can't even pin down the century. Help?Thanks in advance!

I already heavily shopped the copper due to it's being very dark in hand.

 

Well... It looks like fakes for me. But it is my opinion only.

 

Based on what details?

 

I don't like details of the coat of arms.

 

The second coin is a copy that is more common than genuine examples. The first one also appears to be a copy.

 

Thank you for your time.
