The coins confirm a contemporary account by Josephus Flavius, a Jewish general who became a Roman historian.
Writing after a Jewish revolt against Rome and the destruction of the Temple by legionnaires in 70 A.D., he recounted that work on the Temple Mount had been completed only by King Agrippa II, Herod’s great-grandson, two decades before the entire compound was destroyed.
This would also explain how the Western Wall survived the prophecy by Jesus - ...not one stone upon another...
It hadn’t been built yet, during the lifetime of Jesus.
I like the way you think. That’s a good catch!
