YOU DON'T NEED TO CREATE NEW THREADS. JUST POST THE NEW PICTURES ON YOUR ORIGINAL THREAD! I mentioned in the original thread that it's a counterstamp.
What they said. Once you have chosen a particular forum to list your post in, do not add it to other areas, as double posts are considered bad form. New members will often post under "Coin Talk" and then because the coin has some questionable area, post the same coin under "Error Coins" but it should only be posted once.
