I think the top one is a Doberman and the bottom a German Shepherd...seriously I'm sure someone will give you a real answer.
Just by the design of the coins, the color is off, and the surface is unnaturally muddled. Most likely replicas sold in a souvenir shop or something.
The fact that it has a dog collar attached to it makes me somewhat troubled ... hey chrsmat, as you probably already know, I ain't no expert ... but *edit* ... ooops, sorry christina, I mistook you for somebody else (but my comments remain the same) Hi => "welcome"
They imitate certain Judaean types, but they're not meant to deceive - just jewelry replicas. The prutoh could possibly be real, hard to tell from the pics.
Rest are fake as well sorry. The top one is a replica of a Judea capta bronze, the bottom ones are replicas of a Silver Shekel, and a Trajan Denarius.
Welcome @christina87. Sorry about the fakes, but, hey, stick around and get yourself some real Ancients.
