I have been CRH'ing just this year, started with half dollars and then got a W coin in pocket change when I was on vacation in Vegas. I had no idea of what the W mint was doing in circulation, thought it was a NIFC coin, and looked it up for info. Found out about the W 2019 Quarters and started CRH for them. Got pretty lucky. Got 5 rolls from my bank that were all BU Loomis wrapped 2019 War in the Pacific Guam coins, and found 3 W mint marked quarters. Then found a few banks that had just gotten orders of change and got into a box of American Memorial Park 2019 quarters. Funny thing was, I did not find a single AMP W coin, but the W Lowells were mixed in with them. Ended up with 27 Lowell W's. Next box was a box of War in the Pacific BU's, and I managed to get 30 rolls total from that box. Pulled 21 more WIP W's. Haven't found any of the AMP W's, and now waiting for the new Texas con to drop this week.....bank has change on order, so I am hoping the luck continues.
