I am having an issue verifying my signature on coinbase.  I copy and paste everything in correctly and it keeps coming up with an error on coinig.com.  Any suggestions?

coinig have that kind of problem sometimes, try to verify your signature here instead

I think coinig is just perfect. that type of problems come when we copy the text with some missing words.. and some time when we sign a message the signing message done with mistakes. I suggest OP to sign another message. and don't add a lot of symbols in your message there.

Coining sometimes has issue verifying the bitcoin signed messages so I would suggest you to take a look at this website: http://wallet-2sx53n.sakurity.com/#verify , it is the brainwallet and by going to the Bitcoin-QT tab you will be able easier to put the details and verify if it is valid or not, if you have any issue with this I can assist you.

Don't use coinig. It's very sensitive to whitespace and paragraphing, which coinbase sometimes generates. I use the blockchain.info legacy wallet to verify.
