Question about scam coins and ERC-20

Hi, I work for a financial newsletter (just customer service so I’m not the most knowledgeable in the content itself as I am in general navigation of our resources). A customer asked a question about a coin they swapped and I’m wondering if anyone has experience with this. She mistook ERC-20 as a coin itself rather than a standard for assets. She showed me her wallet and it does look she has a coin called ERC20 in her coinbase wallet which I didn’t think would be possible. Is this a scam coin? Can she get that money back?
