If you are in a city, you may find numismatic clubs around.
Be in touch with them, they generally tend to be helpful.
At a time we had numismatic exhibitions in our schools, social interaction and discussions were good part of that hobby.
I have a collection from several decades back, started with fascination towards copper ana coin found in grandparent's wooden-chest-box.
I think I have coins for around 65 countries, many of them out of circulation decades earlier, haven't touched for decades that some got blackened out.
