Malaya 1942 50 Cents Block MB Japanese Invasion Money

***Nowadays all types of banknotes are being sent to PMG for grading even though some or rather, many of these banknotes are inexpensive ones, giving the impression that it's not that expensive to have had banknotes graded by PMG or that PMG belongs to one's grandfather.
Take this 50 cents JIM as a fine example as it is currently catalogued at RM20 a piece, that is, mind you, for a UNC piece, and an AUNC piece would, naturally, be priced very much lower than that, so, why send such a cheap banknote to PMG to be 'slabbed' unless of course, PMG must be owned by one's father or one's grandfather.
