@ Numismatic student:- I respect your knowledge in other areas of numismatics.

No need to be intimidated when it comes to ancient Greek coins - just be prudent.
If you are starting out into ancient Greek coins, just make sure that you only buy from well established specialist dealers in ancient coins.

The very first ancient Greek coin that came into my collection was may my avatar coin. I bought it directly from Spinks London, way back in 1980.

I had been collecting lower valued Roman coins (which are far easier to understand), for some years before developing an interest and basic knowledge, by reading up on the history of the Roman Empire, and was a subscriber to their (Spinks - 'Numismatic Bulletin') coins for sale as well, for a couple of years before then. 'Roman Coins and their Values' provides a great introduction to Roman coinage.

Same for ancient Greek coins, I read up on the history of the ancient Greeks, before buying specialist books on ancient Greek coinage, such as 'Greek Coins and Their values' by David Sear. For current pricing, I did fair amount of research on VCOINS as well, when that information became available on-line.

I have been regularly attending specialist numismatic public auction view days for about 30 years, to closely inspect and become familiar with ancient coins of all cultures. Also gives me a good idea of current pricing.

I support my general numismatic interests with about 200 specialist books and research papers, that have an emphasis on ancient coinages. My numismatic library has taken about 40 years to put together, buying books as I needed them.
My learning curve is still steep, and I still need to rely on the specialist knowledge of other CCF members.
