Nice little bit of doubling under the L of LIBERTY and above the 7 of the date. Not a super strong one but decent enough. The die marker is the die gouge under the last S of STATES, although I would place this one at an unlisted stage B due to the loss of most other stage A die markers.

And, if you would like to own this very nice coin, I will send the exact coin shown to you free including shipping. All you have to do is be the person who sends me a PM as described below.
The only constraint is that you must have at least 250 posts to meet the board's buy/sell/trade rules. If you've got that, you qualify.
The coin will go to the person who sends me the first PM after 11am on December 12, 2018. Even ten seconds before 11am and it doesn't count, as it has to be at, or after, 11:00:00 am. Time is current Eastern Time. That should be late enough to give the western folks half a chance.
The PM must include: The country, year, and denomination of a coin with a bat on it. Commemoratives and others all count, but it has to have the three items listed and a bat of the flying mammal kind in the design.
Good luck! I will post the winner as soon as there is one.
