Congratulations on finding Black-4! I made these coins as a free way to enjoy trackables, if you took the time to log one of my coins, I sincerely thank you and hope all your hunts end in smileys. Stay tuned, I will soon be placing more geocaches of my own, and my coins will be game pieces that give clues to a hidden horde of a cache, check back often as around mid-2015 any coins still in circulation will be assigned their game piece, you don't need to hold on to the piece, go ahead and place elsewhere and check back on this page for the game piece! There are three ways to pass this coin along: 1. Scan the QR code and drop it in a cache, it will fill in the coordinates automatically. 2. Place in a cache, then type in the tracking number on the main page and hit the drop off button, copy the coordinates from the official cache page and paste into the coordinate field. 3. Give it to a cache friend for them to log and pass along! Feel free to message me on geocaching.com, userid: Plates The Hunter.
