If you have an autographed sports jersey, it only makes sense. Like every other item of value, your number one priority is obviously going to be to take the appropriate steps needed in order to fully protect your investment. If you are looking to preserve your autographed jersey your best bet is to purchase an appropriate display case in order to not only protect the item but have it in an area in your home where you can see it regularly. Here are some ideas you should keep in mind for finding the best display case for your autographed jersey: 
1. Invest in a display case that treats light correctly
When it comes to your autographed jersey, light can either have a positive affect or a negative one. When selecting a display case, the first thing to keep in mind would be to identify a case that will both allow enough light for you to thoroughly enjoy the artifact but to also protect the collectible from the harmful UV rays that can cause the signature on the jersey to fade. Thus, the best display case to consider would be an example that is made of a special type of glass with special coatings.
One great example that is popular on Amazon would be an acrylic example. Many of their listings are under $70. This one
2. Purchase a display case that allows for proper air circulation
An autographed sports jersey is a rather unique item because it is usually larger than a card, helmet, football, baseball or basketball. Because of this, the jersey will need room in the case to “breathe”. The jersey can become damaged when it is pressed up against the case. Usually, most collectors think it is wise to allow at least a half inch from the glass to the display itself. Many popular choices that allow for great air circulation are advertised on eBay. Some of these would include examples with hinges, and another example population on the auction would be one that includes a shadow box allowing room to store other related autographed items as well. 
3. Keep climate in mind when storing your jersey
Even with a good display case, storing your collectible in an area with a lot of moisture is an unwise idea. It is better to store it in an air conditioned living room than in a garage.
In conclusion, there are many jersey display cases to consider, including examples which have a team logo emblazoned right on the front for under $200 at many well-known retailers such as Amazon and eBay. You can find those here.
You can also buy cases where you can see both sides such as this example with a mirrored back.
