1964 Kennedy Half. Are These The Same Coin?

The majority of coin errors we see here, if indeed were errors, would fetch at best only a few dollars. We would love to see real errors, not just pocket change guesses. Most beginners approach the hobby backwards and hope every coin they have are error coins. They search for errors everywhere, from the floor of their 7-11 to the free cent tray at the gas station. Looking for error coins this way is disappointing because rarely is an error coin found.

A better approach would be to learn how coins are made and buy a couple of boxes of cents from the bank. Look through hundreds and thousands of coins and look for anything unusual. Error coins are difficult to find, error coins are rare! Not every coin is an error coin! Learn what an error should look like and know when you find one, don't guess! In addition to sorting cents, look through older pages of coins here on CCF, a totally free and valuable resource! Ask questions and learn the glossary of error coins. We are really happy to help you out, but we can't do the work for you. All the experts here will tell you the same thing, this hobby is hard to learn, but very rewarding. Rewarding rarely in riches, but in knowledge gained and in sharing with others. There are no shortcuts and as I said, not every coin is an error coin, but they are out there!

@merclover straight and clear explaination.

Just in case someone actually got interested the top right coin is a regular business strike. I think we can agree it's not the same. The bottom. Left coin is a proof coin. It's not quite like that one either.....right? So if it's not either or? What coin is it? That was my last question and I'd like to thank you guys again.

Please categorize the coin in question.

(I don't do halves much but guess I was right when I was wondering if the point of this thread was looking for an SMS half.)
The coins in your first image are not struck from the same dies.

(See the comparison I put together from your image.)
The finishes are different, your coin has multiple die scratches/dings, and the folds in the upper left part of the ear seem to be different as well. (I don't think it is the lighting or quality of the images making the coins appear dfferent.)

Interesting about your grandfather and hope this reply helps.
It sounds like an interesting group of coins, so I hope you will find more to post.

(ps. And I understand your frustration but let us know if you really want straight answers? We tend to like straight (non-trick) questions.

There is a lot of "reactive knowledge" on this forum where members know the answer because they've been collecting and helping answer questions for a long time. We would love to be on a thread that turns out to have an authentic SMS coin or two.

But we get questions about SMS coins about once a week and the answer isn't what the poster wants to hear. Newer collectors want more details and explanations as to why. It can take a lot of time to put a reply together that makes sense to newer collectors.

FWIW- We aren't very receptive when we feel like we've been played or manipulated with trick questions.

Thank you fellas.
