translation and a brief history about the man on the coin.
The 1966 Bahamian silver dollar was issued as a commemorative coin to mark the Royal Visit of Queen Elizabeth II to the Bahamas. Its value depends on its condition and rarity, but generally, it can be worth around its silver content value or slightly higher to collectors. It's recommended to check with a coin specialist or collector for a more accurate valuation.
Is this the 1960/1970's project wherein oil/energy companies discovered that if a well was drilled past 38000-feet anywhere oil or natural gas would be found in commercially viable quantities??
There is evidence of crop circles throughout the 20th century and even earlier, although the evidence becomes less robust the further back one looks. There are eye-wtiness reports of crop circles on record which date back to the late 19th century, and many more throughout the early decades of the 20th. Some of these reports stem from scientific journals, some from the popular press and some from official documents such as the US Government research, Project Blue Book (1952-69). There is claimed to be a photograph of a circle from the 1930s in an archived book about Sussex, England. The earliest readily available photograph of a clear circle is from Australia in 1966, although it is in reeds on top of a pond, which differentiates it from the usual phenomenon. The earliest image clearly showing a swirled crop circle on land is from 1976, and was photographed in Switzerland.
Within the United States, laws and efforts concerning the preservation of archaeological contexts began as more general decisions. The first of these was with a law in the 1880's near Casa Grande, Arizona, which stemmed from the prevalence of looting in the area. The next step came in the formation of national parks in the 1890's, which protected both environmental resources and some cultural resources. In 1906 the Antiquities Act was passed by Congress, giving the President the authority to designate National Monuments, which protected sites from looting and vandalism on fear of legal sanctions. It also required one to gain a permit to excavate federal land. Another large step occurred in the early 1920's when places could be deemed protected "environments" if they were important to American history or culture. These kinds of places included Bourbon Street, New Orleans, Louisiana and Charleston, South Carolina. The Works Projects administration (which lasted from the 1930's to the 1950's) also provided lots of data from the swiftly undertaken archaeological research done before major projects, such as dams and reservoirs. However there was little analysis done on the data collected. Also in the 1930's, the National Trust for Historic Preservation was formed, protecting historic buildings by buying the properties and restoring them for the future. Then the National Historic Preservation Act of 1966 established the National Register of Historic Places as well as State Historic Preservation Offices (SHPO), which are integral for current Cultural Resource Management archaeological projects. Also as part of this, under section 106, all projects using tax dollars are subject to these stipulations. Finally, the National Environmental Policy Act of 1969 was passed to protect environmental, cultural, and historical resources. This requires any federal project or property slated for development must be checked over by a specialist to see if they are going to negatively impact any resources (environmental, cultural, or historical). This must be declared in an EIS--an environmental impact statement. These various actions have contributed greatly to the preservation of archaeological environments in the United States

It's worth about $4 for its silver content.
It's currently worth about $4 for its silver content.
It is a quarter of a Balboa, the unit of currency in Panama.
Silver Australian coins were first issued in 1910 and were made from sterling silver which has a 92.5% silver content. This changed from 1946 onwards and the silver content was reduced to 50%. No Australian general circulation coin has had any silver content since 1966, except for the round 1966 50 cent coin. The silver content of the older predecimal coins possibly values the coins at more than face value, however, if the coins are in good condition, the collector value may be higher.
The 1966 Mexican peso is about ten percent silver so its value fluctuates with the silver market. Its value also fluctuates depending on the wear of the coin.
The short answer is 1966. Australias last "silver" predecimal coins contained 50% silver. The last of these coins were minted in 1963 and 1964 and were withdrawn soon after decimalisation in February 1966. The only Australian decimal general circulation to ever contain silver, was the 1966 (round) 50 cent coin which had an 80% silver content. Due to the soaring price of silver a short time later, and with the benefit of the wisdom of hindsight, this was a terrible blunder since the silver content of the coin was worth much more than 50 cents, and these coins were withdrawn very quickly.
The 1966 Philippines 25 Centavos is composed of copper, nickel and zinc, with no silver content.
The 1966 Panama 1/4 Balboa coin, also known as the "cuarto de balboa," is a silver coin issued by the Republic of Panama. It has a weight of 6.25 grams and a diameter of 23.5mm. The obverse side features the profile of Vasco Núñez de Balboa, a Spanish conquistador and explorer, while the reverse side typically displays the national coat of arms of Panama. These coins are popular among collectors for their historical significance and numismatic value.
My best guess is that your coin is a one-half ("medio") balboa piece from Panama. Panamanian balboas track the U.S. dollar on a one-for-one basis and are struck on the same planchets. Your 1966 coin was thus struck on the same 40% silver blank used for Kennedy halves of the time, so it would be worth $3 or $4 for its metal content.
Zero. A 1966 U.S. quarter is 0% silver.
Silver coins dated before 1920 are sterling (.925%) silver. Dollars, half dollars, quarters and dimes from 1920 - 1966 are all 80% silver by weight. An easy calculation to figure out the pure silver weight: Multiply .6 oz per dollar of coinage. Example: $10 of 1966 dimes would be .6 x 10 or 6 oz's of pure silver. Multiplying the total by today's price would give you "melt" value of the coins.
