While playing darts to decide who goes first when a singles match is tied.
So many times the coin will be tossed and either goes under a table, stool or other or just isn't easily visible because of the lack of light at floor level in venues.
Hence I thought I'd make a simple one.
The only extra I added was a metal flat washer inside to give the ‘coin’ the weighty feel of a coin. 
I'm adding V2 as the outer ring was flat and was able to land the coin on it's edge. NOT the scenario you want in a heads and tails toss lol.
