The ingot appears to be of Roman origin. It weighs 36.9 grams, which puts in the range of 10 denarii. The dimensions are, 34 mm long, 15 mm wide, and 11 mm high. There is a stamp that was applied after the casting. There are letters present, but due to the very dark patina, they are somewhat difficult to decipher. They appear to be "AECS". This ingot is an interesting example of how Romans stored their wealth. Given the really dark patina on this example, it is probable that it came out of an archaeological find, but where and when we'll never know, which is a shame, since information on any associated objects found with it would help to date it and perhaps even narrow down where it was produced. Does anyone out there have more information? Please post your ingots and hacksilver pieces. From the estate of Guy Clark. Also, greetings from sunny California, at 2 PM.
