Welcome to the Forum @daniel24.

Looks like 3 different coins, all of them of Byzantine types. As for authenticity, I'm not personally qualified to offer an opinion but we have a number of experts here who might be able to help with that.

It's very important, when asking questions of identification or authentication, to give the weight of each coin in grams.

I also won't comment on authenticity: assuming genuine here are some rough estimates of what you could expect at auction if selling

#1: Heraclius Solidus 610-641 Constantinople mint

#2: Phocas Solidus AD 602-610 Constantinople mint (assumptions made without seeing the reverse)

#3:  MAURICE TIBERIUS Solidus AD 583-601 Constantinople

Total value : $1100-1400 for all three - these are decent looking coins but all have some significant flaws encrustations, weak strike and wear

seeing the weights for each of the three in grams and reverse on the second coin might change the estimate.

I concur with @Sulla80 The current standard work for identifying Byzantine coins is Sear, David. Byzantine Coins and Their Values. (London, 1987). The largest collection, available on the internet is the Dumbarton Oaks Collection (DOC) https://www.doaks.org/resources/coins/catalogue#b_start=0 There are also other databases you can search by the emperors name like:

For identification I also propose to use this database:

The first coin is probably Sear 734 with the officina (mintmark) worn away.

The second coin is probably Sear 618, but since a reverse picture was not posted it may be another variant.

The third looks like Sear 478.

A happy numismatic New Year to you all!
