Canada. - 1000 Dollars 1988 - Pick 100a

This is the Canadian 1988 Bird Series 1000 Canadian dollar banknote, the largest circulating banknote in Canadian history, now officially withdrawn and classified as a collectible-grade note.

Key background: Why has this banknote ceased circulation long ago?
1. Issuance and Discontinuation: Officially issued in 1988, officially withdrawn from circulation and redemption in May 2000, and no longer allowed for market transactions.
2. Core reason for discontinuation: The denomination was too large, making it highly vulnerable to money laundering, illegal gang transactions, and large gray money transactions. The Bank of Canada, in cooperation with police and anti-money laundering regulations, directly abolished the 1,000 Canadian dollar note, and never issued the 1,000 Canadian dollar note again.
3. Fiat status: In theory, it still has legal tender status and can be exchanged at the Bank of Canada for an equivalent Canadian dollar, but almost no one does this — the market value for collecting is much higher than the face value of 1000 Canadian dollars.

This is a circulated banknote with creases on the banknote, so its price is lower than that of a brand-new one. However, it remains a niche and popular collectible foreign currency, with its surviving numbers decreasing year by year, making it a rare type among Canadian banknotes.
Additional trivia
In Canada's subsequent new banknote system, the highest circulating face value was only 100 Canadian dollars, making the thousand-dollar bill a historic currency and a classic "large-denomination out-of-print note" highly recognizable among foreign currency collectors.
