Pretty much all my ancient coins I buy from local dealers or coin shows, after seeing the coin in person. I've also bought a couple of coins from forum members, and I've also bought from FORVM, a US-based ancients dealer. I'd only buy an ancient coin "cold" from ebay with great reluctance - there's just too many fakes, frauds, scams and coins of questionable provenance.
I think the only "catalogues" that attempts to list values of as many different coins as possible are the Sear books. currently there are two volumes of Greek, four Roman (the fourth is yet to be printed, so for late Roman, you need to buy an older book), one Greek Imperial (which isn't very comprehensive for such a vast series) and one Byzantine.
You can also get some values from recent sales of similar coin off sites like Wildwinds and CoinArchives, or the FORVM database of past sales, but it can be pretty hit and miss as to whether your particular coin is listed on either site, or not.
