3. Nomisma Reconciliation
Based on Keyword search: preferred, alternate labels in all
languages and definitions.

4. OCRE Reconciliation
Based on the "Title", which includes the number itself and the mint or authority (or portrait,
depending on volume). Optional properties include: Authority, Mint, Denomination,
Portrait, Issuer, etc.
These properties could be keyword or exact match (recommended for accuracy, but after
reconciling these to Nomisma English preferred labels first)
RIC 1 – 5: Section headings based on authority/portrait
RIC I (second edition) Augustus 1A
RIC II Hadrian 18a
RIC II Hadrian 18b
RIC II Hadrian 2A (aureus)
RIC II Hadrian 2A (denarius)
RIC V Gallienus (joint reign) 2
RIC V Gallienus and Salonina 1
Multiple sections in RIC 5,
empresses in separate sections
vs. earlier volumes
2A in RIC was split to two URIs
in OCRE for denomination
Lower case letters were
designated subtypes, but there is
no Hadrian 18 parent type

5. RIC 6 – 9: Mint
RIC VIII Treveri 14
RIC VIII Lugdunum 14
Multiple numbers per ruler (both
Constantine II): mint required to
improve accuracy
RIC 10 – Section heading, but somewhat sequential
RIC X Arcadius 1
RIC X Theodosius II (East) 201
Theodosius II 201 begins after
Arcadius 159. Following emperor
begins at next hundred mark.
