Well I got the Topic title changed to "Quarter" instead of "Penny". I just switched over to looking at some pennies right before I posted this so I had Penny on my brain which is getting old.
Marve65 - I did do a good warm water wash on this coin thinking the same as you so I think the lamination issues are legit.
Looks to be a planchet issue--perhaps a form of 'surficial exfoliation'. Before running down that rabbit hole, suggest giving the quarter a good soak in 100% acetone. If it's a dried glue-like crud, acetone may reduce or eliminate it.
