Malaysia 2012 Installation Of The 14th King Proof Set Of 3

***The 2 previous similar issues have chartered unchartered territories pricewise & looks like this issue is following suit, even though its mintage is very much higher.
Looking around, you hardly see this Set Of 3 being put up for sale online of late. Where have the 500 boxes gone to?
Historywise, the previous 2 similar issues have been rather popular among collectors and this current one could be the same, unless of course, some Smart Alecs could enlighten us otherwise.
Oh c'mon, don't spew the usual crap that some 'unscrupulous' dealers are hoarding them as one does, indeed, gets tired hearing this same old tired crap.
