The coin in the 4th picture isn't ancient, its a copper solidi of John Casmir II of Poland (1648-1668), the coin with a hole in its center isn't ancient, its early modern, the coin is a Qing dynasty copper cash coin (1644-1911), the chipped coin is just modern foreign currency, and the coin in the slab could be ancient, but a cull, and unidentifiable.
Welcome ob3rst1337! I’m glad to see your interest in ancients. The nice thing about ancients is that many of them are still remarkably affordable. Take your first coin, for example. A budget issue of Constantine. But I can’t make out a lot of detail on that Constantine issue. Look at this great Constantine commemorative for only $15. It still has very good detail and nice highlights. https://www.vcoins.com/en/stores/da...veiled_and_standing_right/491582/Default.aspx I think you’ll enjoy ancients more by holding out for coins with good detail; you can still do so on a limited budget. The dealers at VCoins.com are generally trustworthy. You don’t have to buy slabbed coins to ensure authenticity. In fact, most ancient collectors avoid slabs.
Nice start, but I think you'll find you can pick up some pretty nice coins for $10-$15 a piece if you start out with late roman bronze issues. After all, they are "ancient" and still quite affordable. Very low grade LRBs aren't worth much, if anything, so I would not bother with those. Good luck in the hobby!
