Key date? Interesting. What is your info on that coin?
I checked a coin book I have at home, and it suggested that if a '13 D is in really good shape it can fetch a bit. This one is in only decent shape, though I am certainly not a "coin grader." The color is not very "coppery," and the details are pretty worn. You can clearly make out Lincoln, and fairly clearly see the date, the mint mark, and most of the lettering; you can also see the wheat on the back clearly, but not the detail in the wheat. That being said, the penny is not worn around the edges, with a nice rim still in place around the coin. Fortunately, there are no scratches or scuffs on it -- I didn't damage it digging, which is a plus! I'll try to get a pic and post it. Anyway, though my lack of knowledge must be cosidered, I rated the coin as "good," which my book said put it at about $1.75 in value. Not bad, if my rating was anywhere in the ballpark. I am really excited to have found it. I have a collection of a bunch of wheaties (not from detecting, just ones I've found in pocket change and several passed down from my dad), but nothing earlier than the 1930s. This is my oldest by far!
Looking forward to getting the Time Ranger. My Sharpshooter needs an overhaul -- electronics becoming increasingly flaky. Will First Texas "recondition" my Sharpshooter for a decent price, I wonder?
Oh -- and thanks for the tip on the shallow digging in old downtown areas. I was surprised. My detector gave a nice, solid ID in the copper cent/dime category, NOT a zincoln, and my detector is usually good with that, so I did expect to dig an '82 or earlier penny or a dime. Did NOT expect a wheatie, when I found it so shallow. I learned a key lesson, which your comments about the seated liberty at 1 1/2 inches further illustrates.
Thanks!
