2. Sports Memorabilia
The price of rare sports memorabilia has steadily risen over the past couple of decades. While investing in sports collectibles, it is advisable to stick to a number of sports. Of course, the autographed pieces always manage to draw in bigger profits. You must be clairvoyant enough to predict the superstars of tomorrow while also being on the lookout for rare items such as the 19th-century baseball memorabilia. The rarer they are, the more sentimental value they have, and the bigger return on investment you can expect.
