The University of Oxford has put RPC IV online. This is a big deal, as it hasn't even been published yet! The best database for provincial coins of the Antonines (138-193AD), with 9,061 images; 13,730 types; and 46,725 total specimens.
It's very handy and easy to use. The only oddness is that there is no way to specify if a search is to be done over the 9000 images or the 46,000 specimens. One does the search, then gets an option to go back and change the search settings.
The RPC numbers are provisional. However, for each result it will give other publications of the coin, so except for previously unpublished pieces there will be a safe, usable catalogue number.
