A number of libertarians have embraced symbols which represent the convergence of anti-state (anarchist) and propertarian, pro-market ("capitalist") traditions. These icons are most widely accepted.
Anarcho-capitalist symbolism Wikipedia
The 'black-and-yellow' or 'black-and-gold' flag is used by anarcho-capitalists and other market anarchists. Like other anarchist flags, this flag is bisected diagonally. The right half in black is for anarchy and the yellow is sometimes intended to symbolise gold, a commodity of exchange preferred by some libertarians, especially those who favor the Austrian School of economics, and often used in unrestricted marketplaces (see gold standard).
The flag was first used in public in Colorado in 1963 at an event organised by Robert LeFevre at Rampart College. Murray Rothbard described it:
For the first time in public some of the group also unfurled the “black-and-gold flag,” the colors of which we had all decided best represented anarcho-capitalism: black as the classic color of anarchism and gold as the color of capitalism and hard money.
The Libertatis Æquilibritas (Latin for "the Equilibrium of Liberty") is a symbol created by Per Bylund used by a few adherents of anarcho-capitalism. It is based on the Circle-A, but also the yin/yang symbol and the dollar sign. The Circle represents the total liberty and freedom only available in anarchist society, the yin/yang represents the balance and equilibrium of a free market, and the dollar sign represents unregulated capitalism. It serves to distinguish anarcho-capitalists from classically socialist anarchists, who oppose capitalism as an inherently unjust and statist institution.
The V for Voluntary symbol (also Voluntary V) was created in 2007.
Some variations of the symbol feature a handshake at the top of the symbol, as an expression of a voluntary agreement.
The inverted circle-A or circle-V are commonly used among voluntaryists, consisting of the capital letter "V" enclosed in a circle, to symbolize the voluntaryist philosophy in harmony with the anarchist's ideal of a peaceful stateless society. The circle-V can be written with the Unicode encoding 24CB: Ⓥ. In addition, the "(V)" can be used to quickly represent the circle-V in ASCII text.
