Any discussion of the coin being something other than a
denarius can only be supposition because of the three possible starting points:
1) The story is a fictional account.
2) Jesus was God and the
writing is the
work of God
3) Jesus was a
man and the writings are an account of
his life
1 and 2 can only be a
denarius.
In the case of 1 the original story teller uses the
denarius as a symbol for an analogy. However, which
Denarius cannot be determined, as we cannot enter the mind of the writer.
In 2 It is exactly what is says it is. No debate possible as God would make it what he wants it to be; a
denarius. Again, which one; you’ll have to ask at the pearly gates.
3 seems to be the trip point. You cannot assume the story as historically true without secondary support which is not available as the other gospels are too closely linked to Mark. We have many, many examples of
ancient writing stretching, altering, and guessing at facts to suit the writer’s perspective, so the story can only be taking in a basic form: a question asked, an object produced, question answered. From here you can play a little with the point of the story. For example change Jesus to a disciple and the impact is less but the point is not changed, change the questioner to a
Roman soldier and the meaning is altered. It
comes off as all about the taxes. Interestingly change the object to any
roman coin and the impact of the story remains the same. Whether a
prutah with TAI
CAP, or an
Aureus the point of the story remains the same, in effect rendering the
type of coin historically irrelevant. (Other than being
Roman).
