For Christmas last year, we give our kids and nephews a planned trip to the Boston Aquarium. To give them something to unwrap, we included these $20 coins for each of them to use in the gift shop.

The file has been optimized for Glowforge laser cutters but should work well with most vector-based cutting tools.

Note: These are not official gift certificates :) simply our promise to allow them to purchase something for around the amount shown.
