Gold Mint and Proof Coin Sets
Up to the early 20th century, mint proof coins were struck to check a coin die for any mistakes or problems. This is no longer the case however. Mint proof coin sets are now created to showcase the very best and highest quality coins. Typically made from silver, gold or another precious metal, they are specifically created for collectors and to be kept out of circulation.Uncirculated vs. Proof Coins
When looking for coins for collection purposes, it's important to differentiate between uncirculated and proof coins. An uncirculated coin is one that has not had any wear, including being touched at all. Even touching one reduces its value. On the other hand, a proof coin is one that was struck with a special die. Also, it is treated so that the raised parts have a frosted look whilst the background has a polished, almost mirror-like appearance.Collectable Australian Coins
When looking for collectable coins struck by an Australian mint, keep in mind that there are many different types. If you want proof coin sets, those go back to the introduction of decimalised coinage in 1966. These collectable coins will not necessarily be gold, however. It may be easier to find gold coin sets from the 1970s through the present.US Collectable Coins
With globalisation, collectable coins from all over the world are within reach to more people. Gold mixed US coins are readily available. Mint proof coin sets go back as far as the mid-20th century and can be purchased as sets or individually.Mint and Proof Coin Sets Around the World
