It is very up to you as to what approach you take.
Some people making the move that you are only feel secure buying slabbed ancients. I have bought many thousands of ancients in 20 years of collecting them and only have one slabbed coin and that is because I wanted the coin and the slab was incidental. If you choose to buy slabbed coins then feel free but the majority of ancient collectors don't go this way as they like to hold their coins.
One reason that people like slabbed ancients is that it gives them the assurance that the coin is authentic. This is due to the fact that there are a lot of fakes out there and there are a lot of fakes out there.
When you start out you should be trying to familiarise yourself with what you like but also what real looks like. If at all possible buy from a dealer or set of dealers that you can trust. This will allow you to buy authentic coin but to learn about the correct stylistic attributes that make the coin real. Handling the coin will help you learn what real coins feel like. This might sound daft but you can feel a cast fake in your hand almost immediately when you have handled enough real coins.
Before buying I would suggest also looking through some fakes databases to see if there are any similar coins there. This is not necessarily to check that the coin in question is fake but will give you another point of comparison between real and fake. If you can get to the stage when you know what the fake is fake and why the real one is real you have made a big step forward. THIS MAY TAKE SOME TIME.
Ask questions.... Posting you coin in a variety of coin forums will generally solicit feedback to questions. You might learn more about the context of your coin than you already know.
If you see a deal on ebay and you think that it is too good to be true then it generally is. This is not always the case and there are always bargains to be found but you need to know what you are buying.
If you do make a mistake and buy a fake don't be put off immediately. We have all done it. Treat it as a lesson. Create a black cabinet of your fakes and copies and learn from them. Why was it wrong? How will I spot it next time?
What do you want to buy? Gold? Silver? Early Bronze? Later Bronze? There a lots of options. Study a bit. Choose a period. Enjoy.
If you are buying from a dealer then you will be paying retail prices. Don't expect to make a profit selling the coins on.
In time you will find a collecting theme or themes that catches your imagination and you can go with it. Don't get stuck on other peoples "rules" about collecting. It is YOUR collection. For example if you decided to collect portrait pieces from the Severan period you could decide to mix Roman Imperial and Roman Provincial coins because that's what you have chosen to do others might restrict a similar collection to Imperial portraits only. Neither of these is right or wrong... they are just different.
When you have decided to make the plunge please share it with us. Perhaps explain why you chose what you chose. I am sure you will get some feedback.
