While much of gold is thought to come in select standard sizes, the Perth Mint offers gold in a variety of sizes. Some Perth Mint coins are also IRA eligible. Many coin series come in varying sizes, although not all come in every size.
One Ounce Gold
One ounce gold coins are of a reasonable size. They are a typical size and most of Gainesville Coins’ sets are available in this size. The Kangaroo series, the Lunar series, the Koala series, and the "Treasures of Australia," series all include one ounce gold coins.
Half (1/2) Ounce Gold
Only slightly smaller than the one ounce coins, half ounce coins are another typical size in coin sets. The Kangaroo, the Lunar, and the "Discover Australia," series' all feature half ounce coins.
Quarter (1/4) Ounce Gold
About half the size of a one ounce coin, the quarter ounce gold coin is easy to handle. The Kangaroo and Lunar series contain 1/4 ounce coins. Some Kangaroos and Lunar series' coins are colorized, as well. Quarter-ounce gold coins allow even those of modest means to diversify their savings.
One-Tenth (1/10) Ounce Gold
Approximately the size of the tip of an index finger, the one-tenth ounce coins have intricate enamel images. These coins are an ideal size for storing, making custom jewelry, and for gold bullion. The Lunar series and Kangaroo series showcase one-tenth ounce coins.
One-Twentieth (1/20) Ounce Gold
The slight one-twentieth (1/20) ounce Australian gold coins, averaging at about 5/8 of an inch, are far from insignificant. Despite their stature, some coins exhibit spectacular patterns. Not to mention, they are an affordable way to get into gold. Only a select few series produce one-twentieth ounce coins.
Collecting a Series
Gaining all or most of the coins in a set is always an exciting feat. The exhilaration of, one by one, getting closer to a full set can be equated to the rush of an adrenaline junkie, for some. However, the mere want for a complete set isn’t the only reason one should collect a complete or nearly complete set. Most coins in a series have individual value, but when comprised into a set, the value can go up. For example, a complete set of Silver Eagle proof coins would have a higher premium than that of a single Proof Silver Eagle. While it is impossible to collect a complete set for some coins, it doesn't mean that a nearly complete set would be of a low premium. Solitary coins are great, but the value of coin series shouldn't be forgotten, either.
