Are you an avid collector or just getting started with collecting valuable items? Regardless, it’s essential to understand what has value, what pieces are authentic, and what to collect now that will go up in value after some time has passed. Here, we’ll share things like sports memorabilia, gold coins and other rare, precious metals from companies like American Hartford Gold, Newmont Mining Corporation, or Coeur Mining, and best stamps to collect that would be a fantastic addition to your collection, whether you display them or sell them for high prices:

1. Stamps

For centuries, stamps have been a collector’s staple. Particularly, old, rare stamps can be worth high prices; for example, British Guiana 1c magenta stamp sold for $9.5 million USD in 2014. If you have old stamps and are wondering if they’re worth anything, you’ll want to look at factors such as their condition, rarity, and if they have any historical significance. Having a stamp collection can be a rewarding pastime and an excellent long-term investment, but you should understand the time it takes to research, acquire, and care for it.

2. Sports trading cards

Many kids and sports fans love collecting sports trading cards, and if they keep them in mint condition, the right cards can be incredibly profitable in the future. If you have any vintage trading cards of famous athletes, you may be able to sell it for a high price. The trading card market is thriving, and modern cards for top athletes should be kept and held onto until their values have gone up—so if you’re decluttering your home, hang on to these sports cards!

3. Fine wine

Good wine and the patience characteristic go hand in hand, as fine wine can take many years or even a decade to see a return. The older the wine, the more valuable it is, so if you have any, don’t drink it! However long it may take for a bottle of wine to become profitable, it is a dependable and easy investment to start out with. Remember, patience is a virtue, and it might just bring you large sums of money in the future.

4. Rare coins

The right kind of coin can be worth well over its face value—you’d probably be surprised to see how much money you could get for a rare coin. One of the most valuable coins, the 1794 Flowing Hair Silver Dollar, is worth over $10 million. Don’t worry, though. If you’re just starting out and don’t have $10 million dollars casually in your pocket (you’re not alone), there are many options for more affordable coins to start out with. You’ll want to look for limited edition coins or coins that have minting errors, as their value often increases with time.

5. Comic books

Comic books are an excellent choice if you’re just starting out a collection—first edition or classic comic books have great returns. If you do get into collecting comic books, it takes some time and some research to understand what’s profitable and what’s not. If you can make do with this and become very knowledgeable on what to buy and sell, you can make some real money.

6. Rare vinyls and records

You may have thought that vinyls were out of style, but they’re back and popular as ever—just proving that there can be value in anything if you wait long enough. If you have any first editions of classic albums or singles, depending on their condition, you could make a good profit.

7. Board games

If you have any old board games tucked away or find a vintage set in good condition at the thrift store, keep them! They could be quite valuable. Although they may not rack up high prices like other collectibles, they can still make you a few hundred dollars. Some examples of valuable board games include the 1966 Lost in Space 3D Action Fun Game, 1962 Haunted House, and 1981 Dark Tower.
