Two databases to identify listed and unlisted late
roman coins.
First, nummus-bible-database including a
search engine and RIC references, that lists late roman coinage from AD313 to AD476. Currently more than 18800 LRC listed. Note that you can contribute to improve it with your own
collection.
Then, siliques.fr, a siliquae database including a
search engine for late silver coinage from AD337 to AD476. Currently 1285 sliquae listed in.
