This is the new Bomber Girls Nation challenge coin. Since Savannah is retiring the previous metal challenge coin, which said specifically Savannah anyway, WDHQ decided to offer out a Nation coin. All the chapters are listed on the back. The coins are $4 each, this will cover the cost of the coin and postage. These are available ONLY to patch-holders, and are NOT to be sold to the public.
