Yes, at that time and to me, I thought 10,000 sets were a bit low too. Singapore has a habit of not releasing a lot for commemorative banknotes, except for the 1990 $50 circulating polymer. However, at the time of the release, it was restricted to 2 sets per customer. If you have the will, you can easily buy more.
I got one for the Philippines 20 piso 2023 issue. As long as I can get them at an affordable price, then I am happy. It was quite expensive when I got it. On the other hand, the 5,000 piso 2021 Victory of Mactan is a killer. I do not have this note as the asking price is just too much. Anything that is over $1,000 I have to step back a bit.....
There are two other notes that I will never get. Just too expensive
Philippines - 100.000 piso 1998 Centennial of First Republic
Thailand - 500,000 baht 2000 Golden Wedding Anniversary. Not sure if anyone can get this note from the bank back in 2000.
Also that Ukraine 50 heiven P125 is a killer too. I do not have that note either. Only 1000 sets were issued and I was offered one a few years ago, and the collector wanted 3 full sets of Australia polymer (A$185 x 3). Not sure if he valued my note at face value or what?
Back then when I got this Singapore $10, I posted a spare note on my site for exchange and no one wanted it. I am glad it turned out this way as it is now worth much more. I was then offered it at cost, but then maybe collectors were not willing to pay S$35 for a FV of $10.
BTW, I won't be adding this Singapore $10 commemorative note here as it asked too many questions, like filling up a loan application form 😅.
