How can you tell if something is 100% copper?

Check the conductivity

If you have access to an ohmmeter, which measures electrical resistance, you can test your copper item’s conductivity. At room temperature, copper’s resistance is 1.7 x 10^-8 ohm-meters. You can be sure that your item isn’t pure copper if the resistance is much higher or lower than this.
