When reading the john/2-15 on expelling money-changers and cattle traders from the temple I went to look up the word kerma/ta κέρματα / κέρμα  which is usually translated as small (bronze) coins. How do we know that? I could not find a basis for this translation.
I have learned about large state next to Egypt that was trading in sheep and cattle, gold and was named ... Kerma.  So wouldn't it be only logical to ask, if these were not the people from Kerma trading?
And so the question is weren't the kerma/ta the money from Kerma?
In another episode Pharisees and Herodians ask Jesus if they should pay the tribute in gold to Caesar Mk 12:13-17 . Jesus is telling them to return the money issued by Caesar to Caesar but does not stop there and proceed to tell to give [the greek half-didrachma and jewish silver money?] from God back to God. This would also makes sense as being considered anointed/messiah/shiny/golden/χρύσεος/redeemer  he would be the one to pay tribute (in gold) to.
This would serve as a perfect parallel to the Temple episode where Jesus is essentially insists on keeping in the Temple only the actual silver for the atonement as per Ex 30:16. And so the African kerma should be expelled too.

Numerous village communities scattered alongside fields of crops made up the bulk of the realm, but there also seems to have been districts where pastoralism (goat, sheep and cattle) and gold processing were important industries. Certain Kerma towns served to centralize agricultural products and direct trade. Analysis of the skulls of thousands of cattle interred in royal Kerma tombs suggest that stock were sometimes brought vast distances,
