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 gained strong collector interest a few years ago for its perceived scarcity in circulation. This example was found during a TikTok Live noodle and remains a talking point among Australian error coin hunters.

Features:

• Circulated 20c.
• Cupronickel composition.
• Found during a TikTok Live Noodle.
• Bubble located above the platypus' right claw on the reverse.
• Likely caused by die breakdown or debris on the die at the time of striking, allowing metal to fill the area.
