Malaysia 1986 $500 ZX Replacement Banknote

***If there is an apt word to describe this extinct & now-never-seen banknote, it should be generously tagged as the Grandfather of the Malaysian Replacement banknotes.
And there's a cause to crow like a rooster as how many of us have actually seen this banknote with our own eyes and/or even feel the embossment of this banknote, ya, a rare banknote if that's what you like to hear?

But I have, and I am going to sleep with it tonight.....
