I buy slabbed coins whenever I find/can afford them. However, the question is what to do with recent issue double OMP coin/medal purchases. I am concerned with the controversial association of white spots and haze following slabbing. I am not immediately desirous of selling my collection. Should I slab them now or leave in the double OMP packaging? Which one is safer for my coins? I define double OMP as coin/medal in rigid plastic coin holder plus pliable plastic envelope. Does the advice differ if it is a single OMP i.e. coin in pliable pastic envelope? Thanks.
