Precious metal collectors understand the monetary value of their investments. Purchasing gold, silver bars and platinum coins often has high returns, and holding onto the metals for a few years can help increase their value. However, many people look at these metals - especially platinum - as mere products to complement beauty. After all, precious metals are commonly used in jewelry making because of their durable properties.

What many investors may not realize is platinum has dozens of influential uses in the world today. Most electronic devices would not operate without a small portion of the metal. In fact, it is used in the production of hard disk drives, fiber optic cables, personal computers, military hardware and high-tech automobiles.

Platinum is widely used in these devices because of its electrical conductivity and strength, and although each machine only contains a fraction of a gram of the metal, the amount of electronic products produced each day creates a never-ending demand.

With the world becoming more technologically advanced and people purchasing inordinate amounts of electronic equipment, manufacturers will be ordering platinum at alarming rates. Investors who purchase the precious metal, whether in the form of a coin or bar, will be getting their feet wet in a practice that could present profitable returns a few years down the line. Experts project the demand for platinum won't be slowing down anytime soon, so now may be the best time to buy.

No matter the size or shape, investors who purchase rare coins made out of platinum, gold or silver are making a sound financial decision. These metals rarely depreciate in value and can be a stable way for people to save money. Consumers looking to jump into the exhilarating world of platinum, gold and silver collecting may want to start out small and build up their portfolios over time to get the most out of their investments.
