1971-D half dollars, Pics of two almost identical coins, cracks and bumps

While searching through Kennedy Half dollars I came across two 1971-D coins that appear nearly identical. On the obverse they both have a raised line by "Dollar", also the spots in the "O" and "D" are the same, the "L" is messed up nearly the same and there are cracks by the olive branch in exactly the same places. Isn't this strange? Should I send these coins in to get checked out and graded? Or not much value here to make it worth the while?

Could have been struck by the same dies. Coincidental but possible.

 

Definitely struck from the same die. The raised line from F to D is either a die crack or a nick in the die. I'm guessing that the 2 halves are uncirculated, because the odds of finding 2 coins from the same die from random circulated coins should be improbable. It's a interesting find, but not worth grading based on just 2 coins from the same die.

 

What you have on the reverse of your half dollar is evidence of a die clash. The die gouges you see inside the D and O of DOLLAR show that the two half dollars are from the same die.

Reverse die clashes on 71D half dollars are somewhat common.

 

BROVO!!'-

 

Love what your saying but both of these coins are"distance relatives" check 2 to 3 clock on inner O

 

Look at pics 1 2 4 3 in that order

 

Early and late State die examples of the same die is what I see.

I agree with @352sdeer, it's die deterioration.

I'm going to say that coin 1 (left photo) is from an earlier die state than 2 (right photo). On the attachments, I overlaid both coin photos:

In the below picture, both coins are opaque. Coin 1 is on top, and you cannot see coin 2 under 1. You can see a crack beginning from the inner edge of O at about 2:30 on coin 1 (top).

In the below picture, Coin 1 (on top) is semi-transparent, so the image of coins 1 and 2 are merged. You can see an additional fine line (see red arrow) looking like a drawstring on a bow (i.e. bow & arrow). This line is coming from coin 2 underneath. I think coin 2 shows evidence of a retained die chip. By the time coin 2 was struck, the die crack (observed on coin 1) had progressed to a complete retained die chip, observed on coin 2.

The bow part of the crack starting on coin 1 overlies the bow part of the die chip perfectly. So same die, different states of die deterioration. There is no telling how many strikes from the early to the late state.

 

You can see these two half dollars are both VLDS (very late die states) with a lot of die deterioration going on. Using the die gouges as markers in the D and O of Dollar you can also see that the two halves are from the same die. You are not seeing a die crack through DOLLAR, it is die deterioration of a clash. See attached photos from an MDS reverse clash. Note the clash through DOLLAR and the Olive Branch.

Not that improbable since they are already both of the same date and mint. Take any two 71 D half dollars at random and the chances of them being from the same die is about 1 in 400.
