Key Dates For Current Coins

wow, that is a huge question. I am sure one of these folks can answer.

Hi Hidalgo, I see your question is 'the key dates for current coins' rather than key dates for a series like Lincoln cents including the older wheat cents. Normally some people put a 'key date' on a list based on its lower mintage compared to the others for a series, and so when you look up those key dates, they tend to have higher values. Example for nickels: 1950-d key date. Based on your question however, I'm assuming you are just wondering what coins to perhaps search for in the modern coins rather than look up each and every one, and of course with modern coins mintages may not really make a big difference in value in some cases, but varieties and errors might. So a book to start like strike it rich with pocket change 5th edition points out some of these varieties and errors that might be more worthwhile than say going by a list of every single variety on a free site like https://www.doubleddie.com/ because many of those might be of low value and time consuming to identify (but is great for the more advanced). To this you could add the Amazon kindle version of CherryPickers Guide to rare die varieties, 2023 Red Book of United States coins large print, browse ebay videos with top lists. Next for learning, you can go to the online price guide of PCGS and browse the values, noting the specific few errors or varieties they also list and you will better be able to know which coins might be worthwhile besides looking for top grades from specific years of uncirculated coins which you will notice might be worthwhile to add if searching beyond pocket change.

But with that said many out there offer lists such as for $5 each here but whether they are worthwhile vs putting together your own based on your own criteria of value I cant say. Members on this forum may post that they have lists as well. https://jbcoinsinc.com/

My focus coins are half dollars, so here is my thoughts for "key" coins:

1998 s matt finish silver
1964 proof accented hair
2019 s enhanced reverse proof

And if you want to call it a Kennedy half the 2014 w 50th anniversary gold.

Won't find many of those halves in circulation...looks like you'll be going through mint/proof sets.

I have been shopping for a 2012 Sacagawea Proof , man they are a bit pricey . Probably considerably cheaper to go with a 2012 clad proof set.

For business strikes, any W mint coins, including the ATB Quarters dumped into circulation in 2019 and 2020.
