Hello,
It is usually nice to give size and weight for identifications !
and even better, to tell they are uniface ... and 6 coins, not 3

1.1 is probably a weisspfennig Ferdinand 1 Kuttenberg
1.2 and 3 same but Maximilian 2. It seems there is no mint mark below the lion so it should also be Kuttenberg.
2.1 ? I don't recognize the monogram
2.2 and 2.3 are hellers under Ferdinand 1 both Kuttenberg too.
You can look in our catalogue and prepare request sheets if necessary. I'll look for reference numbers in Markl and Dietiker then.
Very nice coins.
Regards,
André
