WE OFFER FREE CHALLENGE COIN, PATCH AND LAPEL PIN ARTWORK AS LONG AS GRAY WATER OPS MINTS YOUR COINS, LAPEL PINS OR EMBROIDERED PATCHES! We do not create custom art as part of our free service. We will take your ideas and images, and create camera ready art from the files you provide. Artwork is free if you’re placing an order. If you start an order and ask for artwork, we will complete the art and make any changes as needed. Once approved, we will put the coins into production. If we complete art and you decide NOT to order, we will charge a $150 art fee to compensate for the time spent working on your art. If you need something custom made, we charge $75 per hour for artwork outside normal layout. Most orders do not require custom artwork and don’t have any art fees. If you place your order at a later date, you will get a credit for the $150 art fee paid.
