My son's PIR was 2/8/13. He has been at NATTC since 2/9/13 and still hasn't received a class up date for ABH. He has taken an interest in collecting those Challenge Coins. I purchased a few to get him started and made a nice oak display for him. But, we are unable to find a Challenge Coin for NATTC-Pensacola. We have checked at the NEX on base and searched online. I found one on eBay, but the flip side was for 'Chief Petty Officer' and listed for $50. We can find NAS-Pensacola and a coin for nearly every other school. But, not NATTC. If anyone can help us, it would be greatly appreciated.
