Experts at CNBC believe that if you hold these tangible possessions for a very long time, they may appreciate in value. For example, you may have purchased an antique piece of furniture that you appreciate, love to look at or use, hold for thirty years, and sell it. You may make a profit. You may also not be able to give it away at any price. But you are able to enjoy using it while you have it. If you focus on a specific genre or period of art, antiques, or other collectibles, you may realize a return if you purchase it with the intent to hold it for a very long term. However, these investments are highly illiquid, meaning they cannot be easily or quickly converted to cash.
