Hello friend, it seems that you sent funds to a wallet that does not have functions programmed to work with that currency.
When that happens, the funds are frozen in that account, as these are smart contracts that cannot be changed.
The only way that might work, is if the contract where the coins were sent was an upgradeable contract.
That way perhaps the developers of coinbase could generate some function that would allow them to extract those coins from the contract, but generally this type of smart contract creation model is used very little for security reasons.
I wish I could be more helpful.
