When I’m asked if you can buy rare American coins, world gold coins, silver eagles, or bullion coins with a credit card, the simple answer is “yes”. But there are only certain dealers or venues that will accept your card. So, it is possible to buy coins with a charge card, if you shop at the places which accept them.
Most collectors I know do not take the time to read entire books on their favorite rare American coins, though I would recommend doing so. There are many great books on the subject.
I entered into the world of American rare coins from the investor background, but quickly became a numismatic. I’m now a little of both, collector and investor. A hybrid so-to-speak.
What makes gold Liberty Heads so valuable is the fact that so many were melted down by the government in the 1930s. As a result, very few original custom challenge coins cost in classic condition remain.
The last half dollar silver coin made was the Kennedy half dollar. Currently there are no new half dollar silver coins being minted. Most collectors of the pre-1964 Kennedy half dollars are holding on to them. However, because there were so many half dollars in circulation, they are now considered “junk” coins by most collectors as they hold very little premium over face value.
When you start getting in to the more difficult-to-find coins, few can be obtained for under $500. For moderately rare silver coins, a good lower end budget is $500 per coin.
Collecting world coins requires a great deal of research on the subject. You can find coin collecting books and guides that will help you get started. There are a great number of world coins that are available for purchase. Pennies from each country are widely circulated. These may be of value to someone who wants to get as many world pennies as they can, but a someone serious about collecting world coins may not want to waste their time with pennies. Don’t get me wrong, there are pennies that are worth more money than others. Most investors with an interest in foreign pennies usually are interested in them for more than just monetary value.
Ultimately, the pure collector should become more of a collector-investor and the pure investor should become more of an investor-collector. I started as an investor-collector, now I’m more of a collector-investor. My silver and gold coin collections give immeasurable joy and they are the most cherished investments I own.
