Me and my dad are starting a ATB quarter set. Any recommendations on what to do?

My advice.... Grab two whitman's off the internet, and go to your bank and load up on quarter rolls!!Enjoy the hunt, and keep us updated!

That's five quarters a year for ten years. Ending this year. That's allot of quarters. My son has the set up to last year. It's not going to be easy.unless you buy all the sets. They have a set of five silver proof quarters for each of the ten years and clad set also.  I would buy the five quarters for each year at one time you will have to find them. I know they sell complete sets also the individual years in the lens. Lots of fun. It's great your dipping it with your dad that will make it more fun!!

Ditto @NumisMaster
I recommend that you get one of Whitman's ATB quarter albums that has P and D from 2010 to 2021
... and grab some quarter rolls from the bank! Those D mintmarks are harder to find, so don't think it is going to be a breeze. Good luck!

Remember buy the right book. You have without proofs and with proofs. There were five each year. My son only bought the silver proof set. So make sure you buy the right book. I don't know how many have P. Or how many are D..if you buy the Uncirirculaded sets then one group of five will be D and one group will be P.

Haha its funny to me.... Over here in utah, we get all the D mm we can ask for, but finding the P State and ATB Quarters is near impossible.

I just collect the P and D. I like to collect circulation strikes

It's easier to find Denver quarters in Vegas than Philadelphia Quarters for sure.

We have the reverse problem here in Virginia. I've seen it suggested that the Mississippi river is the boundary on D vs P coin distribution in the country, but that isn't confirmed. I wouldn't hang my hat on that but it seems to make sense.

So. Cal. is all "D" coins.
