What’s the deal with the denomination of NT$50? Currently we have:
- [*]A bank note[*]The thick gold colored coin[*]A large coin with a gold disc surrounded by a silver band of dissimilar metal[*]A large gold colored coin slightly larger than a NT$10 coin (just introduced)
[/list]Why have four, without withdrawing previous versions?
As I know the only other coin with more than one variant is the NT$10, but the differences are subtle and only involve the design. It would be easier to follow if the coin designs were radically different in size or shape, but they are all rather large and similar.
