Buy 5 oz Silver Coins – 155 Grams of Fine Silver, Exceptional Collector Formats

The 5 oz silver coin contains 155.517 grams of fine silver and with 39 products at CelticGold occupies the premium middle ground between the popular 2 oz collector format and the large 10 oz. At this weight, coins take on near-medal proportions – typically 65–75mm in diameter – providing an extraordinary canvas for numismatic artistry while still fitting in standard collector presentation boxes.

The Perth Mint's Dominance at 5 oz

The 5 oz silver coin format is overwhelmingly a Perth Mint speciality. The annual programmes that benefit most from the 5 oz canvas are those where wildlife detail matters most:

The Kookaburra 5 oz series – available in multiple annual issues – renders the laughing kingfisher's plumage and beak in extraordinary depth across a coin face the size of a large watch dial. The Koala 5 oz similarly captures the fur texture and tree-branch setting of Australia's iconic marsupial with a sculptural precision impossible at smaller scales.

The Lunar 5 oz pieces from both Lunar II and Lunar III cycles represent some of the Perth Mint's finest annual-design work – zodiac animals rendered with full 3D relief in coins that are genuinely impressive to hold. The Dragon (2012 and 2024) and Rat (2008 and 2020) are the most sought-after years.

FAQ

Who typically buys 5 oz silver coins? Collectors who want the visual impact of large-format coins without committing to the storage demands of 10 oz or 1 kilo pieces. Also investors building Perth Mint annual-design sets across weight ranges.

Do 5 oz silver coins carry lower premiums than 1 oz? Per-gram premiums are typically lower at 5 oz than at 1 oz for the same series, as fixed production costs spread over more metal. However, collector premiums for rare years (Dragon, inaugural issues) can significantly exceed spot value regardless of weight.
