Naval Special Warfare SEAL Team Ten / 10, 1 Troop Navy Challenge Coin

The images show side by side comparison of the actual troop or real challenge coin to the fake coin which was made.  

The fake coin's quality is not very good and almost feels like you are holding a plastic coin it is so light.

There were quite a few of these sold on eBay around 2016-17 time-frame, didn't see one for nearly two years and one showed up for sale in 2019.
