2010 Twenty Cent “Bubble” CUD Error – Royal Australian Mint.

This circulated 2010 Australian 20c coin features the well‑known “bubble” above the platypus’s right claw — a CUD (die break) error that drew strong collector interest for its perceived scarcity in circulation. Found during a TikTok Live noodle, it remains a popular talking point among Australian error‑coin enthusiasts.

Features:

• Circulated 20c coin.
• Cupronickel composition.
• Originally found during a TikTok Live noodle.
• Bubble located above the platypus’s right claw on the reverse.
• Likely caused by die breakdown or debris on the die, allowing excess metal to fill the area during striking.
