"Money Spectrum" - Where Is Your Line In The Sand?

I went with the specific countries choice, but with an asterisk. I'm pretty strongly focused on US coins. I have nothing against world coins, but I'm an American in the US so it is a natural starting point. There are far more US coins that I want than I could ever afford, so it doesn't make sense for me to expand my horizons too far.

That being said, I could see myself getting into Ancient coins. Whenever I go to a museum I always spend the most time in the early civilizations section (Roman Empire or older). Something just fascinates me about man made objects that aren't just a couple hundred years old but a couple thousand years or older.

I can imagine!

The more common ancient coin types (such as LRBs - that's Late Roman Bronzes, for dd27's record) are literally orders of magnitude cheaper than any non-coin objects of anywhere near comparable age. Even the 16th-18th century coins are, when not very rare, a good deal cheaper than any non-monetary object from the same century.
(Sure, that's because so many of them were made, but that doesn't make them any newer.)

Ancients are easy to get sucked into. You can go onto ebay and buy nice (collectable) Constantine the Great bronzes, problem-free for less than $10 each.

Heck, you can buy an XF/AU denarius from each of the five "good emperors" (Nerva, Trajan, Pius, Hadrian, Aurelius) for the price of a semi-key Morgan.
