Found two uncirculated bundles of HCR25 a few days after Christmas. Nothing UNC since then, but new serial ranges popping up are mostly HCK8, some HCM23, and surprisingly a few older HCE47 and HCF98. Tens of 2013 series I am finding lots of FTN3, FTR36, FTT29/30 and yes a few FTU0 here and there. 2018 series lots of FTW07, 09, 25, 26 and FFA12, 39, 40. FTY and FTZ I have spotted singles of so I assume they are travelers.
What HCH are you finding? I am assuming 0, 7, 9 or possibly 8 because those are the ones I have found very difficult to find.
