The USMMA Midwest Parents' Association has the challenge coins for sale. But, I just looked at their site and the 2018 is not listed for sale. I would contact them to find out if they have some extra. Go to the USMMA National Parents' Association page www.kpparents.com and you'll find the links to the various state associations. The contact person is Han Ko, usmmamidwestpa@gmail.com Good luck!
