This photo is of someone's life savings.
The unfortunate person had buried this money to keep it for future use, but was never able to use it. The "hoard" was eventurally discovered in modern times in modern England. The "newest" coin in the hoard is from the reign of Roman Emperor Claudius I, who ruled during the time when St. Paul was active.
In other words, we have here a collection of coins like those that St. Paul could have earned and carried and spent.
Money was just as important in the ancient world as it is today, and I have added a page to this web site in which I present evidence that a day's wage in the Roman Empire had the same relative purchasing power as it has in our day. Navigate over to that tab and see if you agree with me.
These coins are displayed in the British Museum as "Hoard of early Roman coins." CM 1985, 10-7-14, 19, 22, 24, 30, 37, 40, 45, 46, 51, 54, 56, 61-64, 70-77. Photo by Richard Davies. You may use it as long as you give credit to the photographer and do not use it for commercial purposes.
