Jamey...the coin was in a vertical position so the hit wasn't as strong as it could have been. The signal didn't waver at all so I knew it was going to be good.
WS Whiting...as you've found out by now (if delivery was on time,) the AT Pro is an easy learn. It's the machine that found this coin.
Dirtscratcher...you said it all! I found no other item of age on this hunt. It must have been a show & tell item that was mismanaged or maybe a kid losing the coin that he had "borrowed" from his parents' collection and then lost. Whatever the reason, there was nothing to expect it being there.
Mi$terG...no, although the posted image gives off such an appearance, it does not have the mint luster. I think the lighting I used to eliminate glare caused the effect.
Thank you to all that took a look at the post and especially to those that took more time to comment. The find was a thrill and your kind responses have kept the feeling going.
