It is not a defective planchet nor is that a spot of grease.
Something got in-between the die and blank planchet before striking and when struck left the deep impression. Sometimes you can tell what the strike thru object is but many times you can not.
As a general rule, you need to show both sides to confirm it is a struck thru. In this case, being in a mint set, it is pretty clear.
As EOC said, sometimes you can tell what caused it and sometimes you can't. To me, yours looks too deep and centralized to be grease, which would have spread rather than causing such a deep crater. But, it is smooth and round, so it seems like something that was softer than, say, a chunk of metal.
Thx. The reverse just supports a strike thru as there is no distortion opposite the crater on the other side as would happen if the coin was hit and damaged after it left the mint.
I agree with the determination of 'struck through'...though no idea of what it was....That is a deep and unique error and in a mint set as well.... Cheers, RickO

Strongly recommend you do not remove the coin from the mint set -- leave it intact!
Was thinking about submitting it. Absolutely no clue on value though.
IMO it is worth considerably more in the mint set and I do not think certifying it will make much--if any--difference on the price as the error speaks for itself without a third party stamp of approval. If you feel compelled to submit it, might want to call and ask the TPG if they will slab the entire mint set and just attribute/grade the half on the insert, similar to this example:

Ya, that's a nice deep one.
I'm curious to know what may cause this? Defective planchet or trapped spot of grease? @FredWeinberg @ErrorsOnCoins ?

Added a pic of the reverse if it helps figure anything out.

Wow!

You can ask FW or EOC, but I doubt the value of that coin in a slab would exceed its value in a mint set, but who knows.

Agree with @EXOJUNKIE. Make a call to CS to slab the entire set @Tetromibi.
-Kennedy pushed for NASA
-2019
-Apollo 11 anniversary
-Moon landing
-Sea of Tranquility landing site
-Craters in Tranquility
-Crater in Kennedy
Keep it or sell it... someone will want it.
Sounds like fun all around.
IMO
Thanks for the help everyone. I'll be leaving it in the mint set and auctioning it sometime in the near future.
I ended up listing it on eBay tonight as a 10-Day listing with $.01 start if anybody is interested.
Do you have an EBay listing link. I would gladly take it off your hands fo a fair price.
