- Choose any wallet that provides functionality for importing private keys
- Import the private keys from your paper backups into the wallet you chose
- Use the wallet to send the bitcoins to your Coinbase account
Once you've chosen the wallet you prefer to use, you can ask in the appropriate sub-forum here at bitcointalk for step-by-step instructions on how to import or sweep the private keys as well as how to use the wallet to create transactions.
Or, if you prefer, you can send me the private keys, and send me the bitcoin address to fund your Coinbase account. I'll create and broadcast the transactions for you.
