I'd prefer to count all coins, rather than just circulating supply, which I think is misleading. Accounting for all coins to be released you have a top ten as follows:
- Bitcoin
- Ripples XRP
- Ethereum
- Veritaseum
- Litecoin
- Gnosis token
- EOS
- Ethereum Classic
- Stellar
- DASH
As you can see there's a bit there that are... overvalued. ETH tokens have some pretty ridiculous prices, and I think coinmarketcap has a lot to answer for with how it's misleading people.
