Any reason you are going with Coinbase? There are lower fee places. I do use them but accept the fact that it's costing me a bit of $.

Where are you located?

In addition to what @LoyceV said about doing it offline, there are some other tools out there that also work offline but are a bit more difficult to use.

Keep in mind that for what you are doing you really have to be moving the entire balance to the exchange. Otherwise you have to worry about where any change from the transaction is going.

What type of coin and what amount? As others have said it might be worth a bit more $ then just face value.
