a number of potential buyers and show them the merchandise. Some habitual thieves are so well known to police that if the thief were to attempt to sell any used goods, this would quickly draw the attention of law enforcement. The fence disguises the stolen nature of the goods, if possible, so that he or she can sell them closer to the market price. Depending on the stolen item, the fence may attempt to remove, deface, or replace serial numbers on the stolen item before reselling it. In some cases, fences will transport the stolen items to a different city to sell them, because this lessens the likelihood that the items will be recognised. However, a disadvantage of trying to sell stolen goods outside a fence's home city directly to buyers is that the fence may not be well-known in the community and thus not likely to be trusted by potential customers whether law-abiding or otherwise. To overcome this, fences often develop clandestine relationships with trusted fences in other locales, thus allowing stolen goods to be easily exchanged in bulk by fences in different cities. For some types of stolen goods, fences disassemble the good and sell the individual parts, because the sale of parts is less risky. For example, a stolen car or bicycle may be disassembled so that the parts can be sold individually. Another tactic used by some fences is to retain stolen items for some time before selling them, which lessens the likelihood that the burglary victims or police will be actively looking for the items in auctions and pawnshops. The prices fences pay thieves typically depend both on norms and on legitimate market rates for the items in question. Vulnerable sellers, such as drug addicts or casual thieves, may receive less than 20% of an item's value. Higher prices, sometimes as high as 50% of an item's value in a legal market, can be commanded by a professional thief, especially one who has managed to remain relatively unknown to police and/or who concentrates on valuable items. Fences may take advantage of thieves by deceiving them about the value of items and the relevant market conditions. For example, a fence may falsely tell a petty thief that the market for the type of good which the thief is selling is flooded with this type of merchandise, to justify paying out a lower price.
