Hello, just got those 2 byzantine coins but its hard for me to identify them. Thank you in advance and have a nice day :)

                                                                                             27mm/6,89g

                                                                                              32mm/12,55g

Second coins seems to be this:

N#143683

or a different follis type. First one is definitely an anonymous follis too but i dont know which type
