1973 P Kennedy Half dollar, Broad Struck or Something Else?

arby96

Hello Everyone, Please check out this 1973 P Kennedy Half Dollar. Is this a broad struck Half Dollar or something else going on. I have seen where the reeding has been filed down between the obverse and reverse. This is the first time I have seen what appears to be a lip over hang on the obverse side of this coin. I know its nothing major its most likely common. Please let me know what might have caused this issue. I measured the diameter and the largest measurement is 31.01MM. It should measure 30.61MM. The last photo is the Half dollar lying face down flat. Thanks for taking a look.

i think the nickname for this is railroad rim aka partial collar. i can't tell if it is partial collar or partial tilted. a tilted won't go all the way around.

It appears to be a "partial collar strike," where the planchet was not all the way down into the collar during the strike and only the part that was above the collar spread out similar to the effect of a broadstruck error.

Edited to add: In the old days this was nicknamed a "Railroad Rim Error," because the spread out flange sort of resembled the flange on a railroad car wheel.

It looks like a partial collar strike.

Yes, that is a partial collar strike. Very cool.

Thank you all for your opinions, I personally haven't seen any of these in person, this is my first I have found circulation. I will go with the consensus. If any of you have photos of your personal Partial Collar Strikes, please share them. It would help a lot helping others what to look for. Thanks

Here are some photos of the reeding and edges of the coin. Just wanted to share these to see if anyone changes their mind or confirms your opinion. Thanks. I used a clock reference using the obverse of the coin. 12 o'clock 3 o'clock, 6 o'clock, and 9 o'clock.

here are 3 sets of photos.

Obverse Edge

Reverse Edge

on another blog someone stated the reeding may have been altered, if that is the case. Here is my Question, if the reeding has been altered wouldn't the entire coin still be the proper in diameter 30.61MM. The largest part of the coin measures 31.01 in diameter

So I took three measurements with a digital caliper here are the results.

Caliper Measurement at 12:30 30.69mm at 9:15 30.58MM. and at 10:20 31.01MM
These measurements are approximate locations.
