Hi,
ETH and ETC are not the same. You have both, but are unable to access your ETC from your typical account dashboard. We do not plan to continue to support ETC, which is why we’re giving customers the opportunity to withdraw it before we end support.

You can read more about ETC and what it is on our FAQ page: https://support.coinbase.com/customer/en/portal/articles/2524725-ethereum-classic-faq
I hope this information helps. Please let me know if you have any further questions or concerns.
