I'm cobbling together a 'short+' set of Walkers all graded MS-65 PCGS from 1938 -1947 & have a dealer offering me a nice 1941-S MS-64+ @ approximately 1/2 the price of an MS-65. I'm tempted, but not sure I care to change the set's collecting paradigm. Does MS-64+ mean simply MS-64.5..or above, but still not MS-65.0 ???? If I'm missing something maybe other CT members can kindly elucidate. Thanks & All the best, J.T.
