A nummus of the type that weighed 1/132 of a pound. It is a single coin from the Seaton Down Hoard. It was made around AD 330-335 and is probably an unofficial copy of a coin of the Constantinopolis type, although the obverse image may not be the personification of Constantinople.
Imitations of nummi were commonplace during the 4th Century AD and, as they were of relatively low value coins, people seemed happy to use them. They can usually be identified by their reduced size or weight, some being much smaller and lighter than the officially minted coins. Alternatively, it may be due to different manufacturing processes, such as being cast as opposed to struck, or due to their much more crude images or finishes. In some cases such coins may have the incorrect pairing of obverse and reverse images. Some of the most frequently copied reverse images are those of the period AD 330-341.
