Note that Chinese sources equate this glyph with 兩, 'rod down insertion in cavity on both sides' and that the elements of this glyph are「person with downward thrusting penis, fucking in spurting stance with two wild dog baculums」that may actually cause a few SPLITS in one's delicate zone skin, or CUTS as it were, due to the motions and activity within juxtaposed orifices combined with both being stretched and filled to maximum capacity, perhaps engaged in the pursuit of MONEY, COIN as all in a day's or night's work.
　「Narrow metal」as COINS. Formerly,「person taking stance with downward thrusting motions by two battling dogs」(per scholars,「two battling lances」) to mean being the「recipient of many cuts.」Later application to small-valued coins or coins of REDUCED value: after coins were minted out of gold or silver, unscrupulous merchants and other schmucks would use a very sharp blade and shave the edges of the coins as a「person in stance of downward thrusting motions making many cuts」and keep those shavings (a SMALL AMOUNT, but which added up quickly and paid better than honestly working), but not creating so much of a difference in the appearance of the coin as to be noticeable, they hoped. By this method the next recipient of that coin was defrauded (as in,「anally shafted by many cuts from battling dogs」) since the amount of metal actually remaining in the coin was less than the face value. For this reason, knurling was added to the outer round edge of coins (all those little vertical lines looking like「many cuts」), so that if a coin was missing its knurling, a recipient would be on notice that the coin had been shaved and devalued, and more importantly, that the other party in the transaction was a schmuck and that all future dealings with that person should be avoided.
