What's the earliest day in the year you found a coin dating the new year? My earliest find was on January 3rd 1993, it was a 1993 Lincoln cent.
How close are you to the mint? I live in South Florida and always see them a few months later at the earliest
I usually find the new year's coins starting late January/early February. Then it is several weeks before I see anything that isn't the new date. Unfortunately this year I have been getting box after box of 2019P cents here in the last month or so. I'm going to end 2019 with solid 2019's and probably start 2020 rolling right into solid 2020's. Blegh.
Give boxes a break and start looking for CWR's. This time of year banks tend to be inundated with CWR's to the point they often dump them out into bags and ship them out for processing because they get so many.
Oh I always make sure to ask for CWRs as well. After I dump my boxes I deposit back at another bank and ask them for CWR. They never half halves though.
