Constantine did not mint denarii. He did, however, make silver coins such as the argenteus. But these can get rather pricey. For Constantine, you'd certainly be better off getting a high quality (EF or so) small bronze. I paid 30 or so for this, it was my first ancient!

Yes, Constantine & other late Roman bronzes are a nice affordable area to collect. Some specific coins can be very expensive, but in general very nice examples can be had fairly inexpensively. You can see my Constantine era coins here. While their are a couple that were pretty expensive, most were $50 or less... http://www.brianeberling.com/gallery/thumbnails.php?album=20
Constantine issued a billon coin, which was roughly 25 percent silver, and these are fairly common and very affordable. http://www.constantinethegreatcoins.com/billon/
Hello JHar4330, Just out of curiosity, I've been browsing two minutes ago thru Vcoins for denarius and under 50 $ and found more than 700 answers... from worn Mark Antony galley denarius to very pleasant ones of Severus Alexander. As a matter of fact it's far more secure to buy from them with guaranty of authenticity and refund in case of a problem than from fleebay. My two pennies Cucumbor
i would also recommend buying yourself a good book or two -- wayne sayles penned several inexpensive introductory books for ancient beginners (including a nice overview of ancient and modern forgeries of classical coins), but for the money, i can't recommend david van meter's 'the handbook of roman imperial coins' highly enough. some of the pricing is out of date, but it gives you an excellent idea of the relative scarcity of each coin. you can find this book at a number of vcoins merchants for around $30. if you really get into ancients and want to persue a particular line of interest, there are other, more specific books or sets of books, but until then, you need van meter. anyone agree, or disagree? also, CNG and pegasi numismatics, among others, have auctions with occasionally inexpensive and nice beginner coins -- and you won't have to lose too much sleep over authenticity when you buy from them. ebay is tough at first. 2 of my first five coins were counterfeits. apparently ancient counterfeits, which is kind of cool, but stil... v.
I don't really want a ton of ancients so I'm not going to buy a book. I'm more likely just to buy a Constantine I one for now.
