Largest Note I've Seen

Went terry's place for mahjong on sunday.. and realised that he actually collect singapore notes. from old currencies to present ones. in a small little file. and it's the first time i knew that there's actually a $25 note in the past.Only knew about the $20 yellowish brown one, $25 seems like quite an odd amount for a note..

Anyway, the main thing about this post is that as terry's parent's were about to leave for work, they showed us this.It's an old $10,000 note (the bird range), quite big in size, somewhere in between a5 and a4... it's the first time i've ever seen real singapore currency in such a big denomination. and it's not a fresh new note, meaning it has exchange hands many times... btw, am i supposed to post this? or do i have to put the word specimen across the note haha..
