I haven't been a big fan of special mint products like that, because they seem more like gimmicks to raise money for the mint than something with real value. I prefer my coins to be old and, as I lightly remove the dirt from them, gleaming with silver or gold!
I am less than uninterested in the 2017 P cents but was shocked to see boxes of brand new 2017 pennies were being bought for 10X face back when they first hit the banks back in March maybe? I was tipped off by Blueridge silver hound's (handle?) youtube. I see it as a lame shortlived but potentially profitable missed opportunity. Oh well. If I see a box I may grab them in case they sell for 10X face again lol.
2017-P cents, with the "P" mint mark. Then in 2018 and beyond there with be no P mint mark, just blank. 2017 will be the ONLY year ever showing the P .
