1918 D Standing Liberty Quarter For Grade

I love this date I just don't run into many original lower grade original skin 1918 D's with at least a readable 2 1/2 - 3 digit weak date. The 1918 D seems to quietly ride the coattails of the 1920 D. This coin and a 1920 P were in old nasty mylar flips rusty staples and all. Seller had a smattering of classic coins but this one and a 1920 P were the only 2 worth above melt. Thanks for opinions.

I agree totally paralyze. I notice some idiosyncrasies within the series that experienced collector'salready know. Picked through Klines book and its a shotgun blast of info. for graduate level collector's.
Kline wrote at a different level above the everyman collector and thats ok, I have alot of respect for his observations. It's a publishing desert for tips and information geared towards the F-VF SLQ hunter Q. David Bowers does cover mid grades but teasingly. Maybe someone will tackle an everyman SLQ book?
My take is yes the 1916 1918/17 S 1923 S get a TPG consensual "pass" and the 1921 1919 D 1919 S get partial pass due to striking scarcity lack of original examples etc etc It's not written in stone but I've encountered "this Pass" its also possibly me over analyzing the peanuts and corn at the puppet show haha. Nah its likely lack of examples available i.m.o.
Love these Quarters as much as everyone else. Frog yes absolutely a 4 digit date is the mark and very sound advice.
