As anyone who is a new Bible student quicky learns, the meaning of 666 is derived from the number and mark of the Beast Power written about in the book of Revelation. It symbolizes the perfection of man's overall system that is separated from God and under the constant influence of Satan the devil.
Man's system on earth is made up of three parts, each represented by a six. Six represents, by itself, incompleteness or imperfection, as it is one less than seven (which is the number of completeness). The first six of 666 represents the false perfected religion of man under Satan's lead. The second six is for the deceived false governments of this world, and the third symbolizes man's self-centered economic system.
Six hundred sixty six represents the world and all that it does to appease and gratify human nature. The book of 1John (written by the apostle John who also wrote Revelation) contains an often overlooked set of three verses which uses a subtle form of 6. This hidden form of six, found in the total number of times the word 'world' is used, warns believers to separate themselves from man's system which is soon to DIE.
15. Do not love the WORLD, nor the things that are in the WORLD. If anyone loves the WORLD, the love of the Father is not in him 16. Because everything that is in the WORLD - the lust of the flesh, and the lust of the eyes, and the pretentious pride of physical life - is not from the Father, but is from the WORLD. 17. And the WORLD and its lust is passing away, but the one who does the will of God abides forever. (John 2:15 - 17, HBFV)

In order to show that the book of Revelation was inspired, Ireneaus (120 - 202 AD), a early church apologist, noted that he had consulted the 'most approved and ancient copies' of Revelation for verification of 666.
How is the number 666 related to wealth?
King Solomon, after assuming the throne of Israel upon his father David's death, soon became wealthy. Although money streamed to him due to the heavy taxation of the Israelites (see 1Kings 4:24), it was the gold that came to him through a variety of other ways that made him the richest man alive. Every year he received a total of 666 talents of gold (1Kings 10:14 - 15), a figured confirmed by the first century historian Josephus (Antiquities (History) of the Jews, Book 8, Chapter 7). The value of these riches today, assuming $1,500 per troy ounce of gold, would exceed two BILLION U.S. dollars a year!
Additional info on the Biblical Meaning of 666
Three people in Scripture stand out as special adversaries of God and his people. Each, in one way or another, has the mark of this special numeric.
Goliath, the giant for fought a very young king David, had a height of 6 cubits, had 6 pieces of armor, and his spear's head weighed 600 shekels of iron (1Samuel 17:4 - 7). Nebuchadnezzar, the great King of Babylon, set up a "golden image" in the plain of Dura. He commanded all who he ruled over to worship it or else be thrown into a furnace of fire. The idol was 60 cubits high and 6 cubits wide (Daniel 3:1). The worship was to occur when six distinct musical instruments (cornet, dulcimer, flute, harp, psaltery, sackbut) were played. The last special adversary is the Antichrist, whose name numbers to 666 (Revelation 13:18).
