Many collectors will talk about the age and distinction of an Antique rug, but as with any antique object its value is only what someone will pay for it. The average customer needs to remember an Antique rug is first and foremost a decorative object. Just as a car's primary function is to move one from place to place; an antique rug should be bought to compliment the room it will go into.
Quality is important. Just as one wants a car that will retain its value, a rug should stand up to normal use. Antique rugs are generally at least 50-80 years old and due consideration should be made to ensure they are in good condition. If the underlying warp and weft threads are showing wear and tear or do not seem to be firmly woven, then the pile of the rug can come off and destroy the entire rug. If the woolen pile is not tied or woven tightly enough, it can also come off during normal use.
If the antique rug is particularly old or valuable then hanging it might be more practical than putting it on the floor where gravity pulls most dirt and debris. Investment grade rugs are very rare, and most buyers will rather be looking at a decorative floor item. Be sure to look at the rug from the correct perspective. One would not want to buy a car too fancy to drive on a regular basis. Don't let the idea that this rug is an investment cloud good judgment.
A valuable, naturally-dyed antique rug might be a good investment, but if the room is full of modern bright colors, it may not look right. Go to as many reputable shops as one can before making a final decision. Varieties of color and styles can be found even among antique rugs and limiting your selection to one shop isn't good from either a decoration or investment strategy. A good quality antique rug should last one longer than a car, and if it is taken care of will become a family heirloom.
Proper care should include rotating the rug and spot cleaning any spills quickly with water or club soda. Occasionally beating the antique rug outside to dislodge dirt and debris from the pile might be more gentle on the edges and fringe than running a vacuum over it. Take time to move the rug around seasonally to prevent wear patterns from forming. This will give one the chance to keep the rooms style updated and the rug in good condition.
