Hi everyone,
I just joined here this morning and did say hello in an existing general thread. I mentioned there that I run rNumis.com. I have a couple of projects I've been working on for some time...resources that you may find interesting. One is a database of historical numismatic auctions (more ancient focused), often with links to online catalogs. The other is a provenance explorer - currently just for Ancient Greek Italy/Sicily, but that can be expanded. There is still a huge amount of work to be done with both projects, but I think there's enough information and functionality there for people to try it out now.
Some of you - thanks @dougsmit and @Sulla80 - have already made some good observations and suggestions. Anticipating further conversation, I'm starting this dedicated thread so we can continue.
Finally, thanks to @DonnaML, from whose post elsewhere I learned about this site.
Cheers,
Steve
