It has been weeks since the release of Singapore limited $20 polymer note. Only a limited 3million copies are printed. This is supposingly a new crave to numismatist all around the world, this new note could be seen in ebay sold higher than it's original note value. Not only so, I have seen many people queued up for this limited notes at the bank. There are even articles in the newspaper about people taking more than the limited 2notes per person.

Isn't this interesting! Collecting notes of the same serial numbers, could actually fetch an extremely high price, when sold together as a set to a numismatist. And even the prefixes does matter. From what I know, the first prefix 0AA and the last prefix would also fetch a slightly higher price, similarly when sold to numismatist.

Isn't notes collecting interesting? Hmm, some people even have olden times coins, such as coins from ancient china. It is really about collecting coins that brings back images of the past, or to have a collection of coins and notes from different era.

Why am I posting about notes/coins collecting? It is because of a curiousity my friend have, "what is the last prefix of the limited $20 polymer note?" Perhaps you can post it on the tagbox, if you by any chance collected a prefix which is larger than 0AB.

Quaver.
