You won't learn much without ever holding one in your hand.
Especially learning to spot
fakes is VERY hard if you don't know what a genuine coin looks and feels like in hand.
Just
pick a reputable dealer and buy a coin.

https://www.forumancientcoins.com/catalog/roman-and-greek-coins.aspAn ancient coin is not a big investment, it's important to be cautiuous and use common sense
but don't be afraid to just buy coins. You learn by looking at coins, touching, smelling, even tasting them.
,
much faster than by just looking at them on the screen or in a book. Especially if you buy
cheap, worn and corroded coins.
You will learn what wear corrosion and
patina look and feel like which will
help you in spotting
fakes.
You will learn to recognize which coins are ancient and which are modern, either casts from originals
or made from modern dies.
If you have the chance, go to a
coin show. There, stick to dealers, whose names you recognize but even
buying from smaller dealers is no problem if you buy
cheap. I wouldn't buy expensive coins from shady dealers
but I will look at their junk boxes. Even if you do buy a
fake, it's not the end of the world, it happens to everybody
sooner or later. I bought my first
fake 3 years after starting collecting, because I was always cautious.
After that I was paranoid for a few weeks, which is completely normal but that was soon over.
A
good coin show is as close to heaven as you can get.
