Thanks. I'll bet most countries have some modern coins with no real book value that are extremely hard to find, especially those countries that aren't as highly sought after.
Malaysia 1971 10 sen is a different story. The mintage of this particular coin is known to be extremely low at 32k ish. You can obtain one of this for around 150USD. Would be extremely hard to find it from circulation as the older type has been slowly removed from circulation.
I have a few others like that that I need for other series I'm working on. 1935 New Zealand 3 pence, 1946 Australia 1 penny, 1925 Australia 1 penny. All of those go for crazy prices.
