2001 PERTH MINT $20 GREGORIAN MILLENNIUM GOLD & SILVER BI-METAL PROOF – ONLY 6,208 MINTED:

An exceptional and increasingly sought-after Australian precious-metal collector coin – the 2001 Perth Mint $20 Gregorian Millennium Gold & Silver Bi-Metal Proof Coin, presented in essentially as-new condition and complete with its original presentation materials.

Issued by The Perth Mint to commemorate the true beginning of the Gregorian Millennium, this unusual $20 coin combines two precious metals in a single striking design, with a fine gold outer ring surrounding a fine silver centre.

Although the maximum authorised mintage was just 7,500 coins, official Perth Mint records show that only 6,208 were actually minted, making this a relatively scarce Australian bi-metallic precious-metal issue.

GOLD & SILVER BI-METALLIC CONSTRUCTION:

• 2001 Australian $20 denomination

• Issued by The Perth Mint

• Gregorian Millennium commemorative issue

• Gold outer ring with silver centre

• Approximately 0.3054 troy oz of fine gold

• Approximately 9.5 grams actual gold weight

• Fine silver centre

• 14.03 gram total coin weight

• 32.1 mm diameter

• Proof-quality collector issue

• Only 6,208 actually minted

The distinctive reverse design incorporates a chronograph-style watch face, astronomical observatory and three representations of the Earth, reflecting the passage of time, astronomy and the beginning of the new Gregorian Millennium.

COMPLETE ORIGINAL PRESENTATION – ESSENTIALLY AS NEW:

This example has been exceptionally well preserved and is presented in essentially as-new condition.

It comes complete with:

• Original outer box

• Beautiful original presentation case

• Original Certificate of Authenticity

• 2001 $20 Gregorian Millennium bi-metallic coin in superb condition

This makes it particularly appealing to collectors seeking a complete example rather than a loose coin without its original Perth Mint presentation materials.

SIGMA VERIFIED – ADDITIONAL AUTHENTICITY ASSURANCE:

For additional buyer confidence, the coin is pictured being tested on my Sigma Metalytics precious-metal verifier.

With valuable gold coins and collectible precious-metal pieces increasingly being replicated, I make an effort to provide additional verification rather than expecting buyers to rely solely on a couple of photographs.

Please refer to the listing photographs showing the actual coin being Sigma verified, along with its condition, original packaging, presentation case and Certificate of Authenticity.
