Commemorative coins are interesting to new and old collectors alike. Commemoratives are generally something of a high-relief proof blend that often contains more modern designs created by newer minting techniques. The coin faces are often contrasty and eye-catching.
The market for commemorative coins changes quickly. Very often "Limited-edition releases" will feature a subject or person you are a friend are interested in, making these coins great for birthday and holiday presents. Combine this with the fact that they are often minted in silver or some other precious medal, and you can see how the market has exploded in recent years.
Supply and demand as usual. If a coin is coveted and popular, but few are in circulation this creates value.
Coins made from precious metals carry intrinsic value.
Coins commemorating major events or figures will often hold value to at the very least a specific group of people.
Coins that have been professionally graded are always worth more, as they provide some reassurance that a 3rd party has given its stamp to the stated condition.
While some commemorative coins appreciate in value, not all are guaranteed to be profitable investments. Market demand fluctuates, what's popular today may not be popular in the future. Worse yet some concepts as strange as it seems, might become offensive to future generations.
Many commemorative enthusiasts collect these coins simply because they enjoy them. The profit being made, is secondary to the "joy" they receive from purchasing and either giving the coins as gifts or adding to their current collection. These coins in that sense are much like pokemon cards if you will.
A coin like the one below would make a great gift to a loved one who served in the United States Marines. This is just one example.
Commemorative coins can be worthwhile additions to any collection. Yes they are often worth the investment, but not solely for financial gains alone. They also have value found in other ways, be it through the gift of giving or the feeling you get when you add to your collection. If you’re the type of person who enjoyed collecting baseball, basketball, or even pokemon cards as a kid, then chances are collecting commemorative coins might be a way to both start a collection, and build something of value for the future.
As these coins are often silver or gold in content, they will always be worth something.
