Welcome to the dark side of coin collecting. Collecting ancients are pretty fun, you can get ones as cheap or as expensive as you want. Lots of resources to read up on here and online. As far as buying goes, start off cheap and familiarize yourself with how they look. The design, portrait, texture and all those things can help you ID a coin and help you determine if its a counterfeit. Also, don't start buying from eBay until you get to know which sellers you can trust. Sites like VCoins are great as most sellers are trustworthy and you can filter your searches more specifically. As your collection and bank account grows you can look into CNG Auctions and other online sites. A few ancient collectors here also sell coins here and online. They have some really nice affordable coins. Hang out a bit and don't get too tempted into buying everything you see here, have fun.
Well, you didnt mention a budget, so all these comments will be all over the place! If one is on a budget, as already posted, there are plenty of mid to late Roman coins that are quite superb and can be had for $10 and up. It may take some time to find the bargains, but it can be done. If budget is not so much of a problem maybe focus on those times of history which interests you, or emperors, gods, goddesses, etc. With ancient coins there is an infinite way in which you can collect. From the focused to the random. One will never regret ancient coins if they are collecting them for the history and connection to the past which they represent. Oh, also, please, please, be sure to put part of your budget into books. They can give one so much more than just searching through websites (content of which often is wrong!). Give us some hints. I have a bag of coins which I intend to give away (was holding them for Christmas, but why not early?). Give me some ideas and I can send a nice coin your way. If in the next few days I can send one off, but I will be on vacation for a week very soon!
When I was starting out, @Bing and @John Anthony we're kind enough to gift me this coin: Constantine I, AD 309 - 337 AE3, 2.5g, 19mm; 1h; Siscia mint, AD 328-329 Obv.: CO[NST]AN-TIN[V]S AVG, diademed head right Rev.: PROVIDEN-TIAE AVGG, campgate with two turretts, star above, 9 brick rows with dots in top row In Ex.: ΓSTS (crescent) I need to reshoot it, this black beauty needs more light.
This is one of the most popular areas of specialty and it is easy to find information about these years. Try to learn as much as you can about all periods from the coin issuing period (lets say 500 BC to 500 AD) and lands from England to Asia. You might find other things equally interesting and be able to be as well informed on them as any of us. Budget is often a question. Below are three coins that might sell for about the same price. One is from the popular Republic; another is from a different era not as well studied; the third is someone you should have heard of but fewer people collect. Which would attract your cash? Those on a budget will face questions like this every day.
