Other anthropologists have questioned whether barter is typically between "total" strangers, a form of barter known as "silent trade". Silent trade, also called silent barter, dumb barter ("dumb" here used in its old meaning of "mute"), or depot trade, is a method by which traders who cannot speak each other's language can trade without talking. However, Benjamin Orlove has shown that while barter occurs through "silent trade" (between strangers), it also occurs in commercial markets as well. "Because barter is a difficult way of conducting trade, it will occur only where there are strong institutional constraints on the use of money or where the barter symbolically denotes a special social relationship and is used in well-defined conditions. To sum up, multipurpose money in markets is like lubrication for machines - necessary for the most efficient function, but not necessary for the existence of the market itself."[12]
Identify your resources. What items do you have that you could easily part with? Use a critical eye to go through your home, and consider possessions you may have in storage or that another family member or friend is currently using. If you would prefer to offer services, honestly assess what you could provide for others that they would otherwise pay a professional to do. It could be a skill or a talent or hobby such as photography. 

Nowinska says one of the biggest challenges Swapsity faces is that new barterers think they have nothing to offer. So they offer bad trades. Yet most people have hundreds of skills—from cooking to networking to scrapbooking. The trick is learning to recognize the value of your skills, your knowledge and your talent. Bartering attaches value to things that are not always recognized, or highly valued, in a cash economy—often hobbies that people can’t make a living on but love to do. One Barter Babe trades her homemade canned goods for gifts—mostly other crafted items—she can give away at Christmas. A Swapsity member has traded pounds of fiddleheads she picks at her mom’s house in the country for feng shui sessions.
Trade did occur in non-monetary societies, but not among fellow villagers. Instead, it was used almost exclusively with strangers, or even enemies, where it was often accompanied by complex rituals involving trade, dance, feasting, mock fighting, or sex—and sometimes all of them intertwined. Take the indigenous Gunwinggu people of Australia, as observed by the anthropologist Ronald Berndt in the 1940s:
Then again, it’s one thing to keep a community alive and well when everyone’s camping in a forest and they’ve all opted in to that vision. It’s quite another to imagine a gift economy enabling humans to build skyscrapers, invent iPhones, put air conditioners in every house, and explore space. (The same goes for collecting taxes and running large businesses.) Not that it’s an all-or-nothing situation: We already have gift economies among friends and family. Perhaps expanding that within small communities is possible; it’s certainly desirable.
Since the latest series of worldwide economic meltdowns, people have bartered in growing numbers. Last year, the 100 members of the International Reciprocal Trade Association, a network of barter and trade exchanges, facilitated the bartering of billions of dollars’ worth of goods and services around the world. (The IRTA uses its own barter currency called Universal Currency.) In some areas of Greece, bartering has become as second nature as paying for things with cash—there’s even a new barter-style currency called the TEM, accrued through offering goods and services via a vast online network and regular open-air market days. Spain’s time bank system, in which people exchange hours of labour instead of units of currency, has grown exponentially as a result of the country’s crippled economy.
Debts in the wir currency, assigned the same value as the Swiss franc, could be paid with sales to any member of the bartering circle: if a baker needed to “purchase” eggs and flour from a farmer, the baker could pay off the debt by “selling” baked goods to another wir member. The farmer, in turn, could use his newly acquired credit to “buy” his own needed items or services. Despite a bank-led campaign to discredit the system, wir stuck. Today, it has more than 60,000 business participants and does the equivalent of about $4.4 billion in annual trade.

On paper, this sounds a bit like delayed barter, but it bears some significant differences. For one thing, it’s much more efficient than Smith’s idea of a barter system, since it doesn’t depend on each person simultaneously having what the other wants. It’s also not tit for tat: No one ever assigns a specific value to the meat or cake or house-building labor, meaning debts can’t be transferred.
