Pure Gold is a 1975 compilation album by Elvis Presley released as part of RCA's budget "Pure Gold" series of albums. Though at this point in his career Presley was focused more on the country music market, where he had a string of chart-topping records in recent years, this compilation focuses more on earlier material than recent hits.
"Kentucky Rain", "Fever", "It's Impossible", and "In The Ghetto" are true stereo mixes. All other tracks are in "electronically reprocessed" stereo. When this album was eventually issued on CD in the early 1990s, the 6 songs from the 50's were restored to original monaural sound.
Original copies (ANL1-0971) show 18 other RCA albums on the back cover. Reissues (AYL1-3732) show BEST BUY SERIES on the front and back covers and do not show the other RCA albums on the back.
The comma-separated values file format is a set of file formats used to store tabular data in which numbers and text are stored in plain textual form that can be read in a text editor. Lines in the text file represent rows of a table, and commas in a line separate what are fields in the tables row. Different implementations of CSV arise as the format is modified to handle richer table content such as allowing a different field separator character, (which is useful if numeric fields are written with a comma instead of a decimal point); or extensions to allow numbers, the separator character, or newline characters in text fields.
CSV is a simple file format that is widely supported, so it is often used to move tabular data between different computer programs that support compatible CSV formats. For example: a CSV file might be used to transfer information from a database program to a spreadsheet.
Example of a USA/UK CSV file (where the decimal separator is a period/full stop and the value separator is a comma):
Year,Make,Model,Length 1997,Ford,E350,2.34 2000,Mercury,Cougar,2.38
Example of a German CSV file (where the decimal separator is a comma and the value separator is a semicolon):
Year;Make;Model;Length 1997;Ford;E350;2,34 2000;Mercury;Cougar;2,38
A file format is a particular way to encode information for storage in a computer file. Particularly, files encoded using the CSV format are used to store tabular data. The format dates back to the early days of business computing and is widely used to pass data between computers with different internal word sizes, data formatting needs, and so forth. For this reason, CSV files are common on all computer platforms.
CSV is a delimited text file that uses a comma to separate values (many implementations of CSV import/export tools allow other separators to be used). Simple CSV implementations will not allow field values that contain a comma or other special characters such as newlines. More sophisticated CSV implementations permit commas and other special characters in a field value. Many implementations use " (double quote) characters around values that contain reserved characters (such as commas, double quotes, or newlines); embedded double quote characters may be represented by a pair of consecutive double quotes. Some CSV implementations may use an escape character such as a backslash to encode reserved characters as an escape sequence.
Comma-separated values are old technology and predate personal computers by more than a decade: the IBM Fortran (level G) compiler under OS/360 supported them in 1967. Comma-separated value lists were often easier to type into punched cards than fixed-column-aligned data, and were less prone to producing incorrect results if a value was punched one column off from its intended location.
The comma separated list (CSL) is a dataformat originally known as comma-separated values (CSV) in the oldest days of simple computers. In the industry of personal computers (then more commonly known as "Home Computers"), the most common use was small businesses generating solicitations using boilerplateform letters and mailing lists.
Some early software applications, such as word processors, allowed a stream of "variable data" to be merged between two files: a form letter, and a CSL of names, addresses, and other data fields. Many applications still do, simply because tasks requiring human input (such as constructing a list) are natural and easy using comma delimiters. CSL/CSVs were also used for simple databases.
Comma separated lists date from before the earliest personal computers, but were widely used in the earliest pre-IBM PC era personal computers for tape storage backup and interchange of database information from machines of two different architectures. In that day, affordable hard drives did not exist, and many small businesses tried to achieve the benefits of computing using floppy disk based software.
No general standard specification for CSV exists. Variations between CSV implementations in different programs are quite common and can lead to interoperation difficulties. For Internet communication of CSV files, an Informational IETF document (RFC 4180 from October 2005) describes the format for the "text/csv" MIME type registered with the IANA. Another relevant specification is provided by Fielded Text which also covers the CSV format.
Many informal documents exist that describe the CSV format. provides an overview of the CSV format in the most widely used applications and explains how it can best be used and supported.
The basic rules from a lot of these specifications are as follows:
CSV is a delimited data format that has fields/columns separated by the commacharacter and records/rows terminated by newlines. Fields that contain a special character (comma, newline, or double quote), must be enclosed in double quotes. If a line contains a single entry which is the empty string, it may be enclosed in double quotes. If a field's value contains a double quote character it is escaped by placing another double quote character next to it. The CSV file format does not require a specific character encoding, byte order, or line terminator format.

Answers:The easy way is with concentrated nitric acid, e.g. "the acid test". It's not something you should try at home in the kitchen sink. there will be fumes, and corrosion. There are cyanide compounds that combine with gold, but you probably don't want to mess with that, either. I am aware of electrochemical refining, which is still messy, or you can get a special kiln that gets hot enough melt gold and burn off all the plastic and stink up the neighborhood. Grandpa

Unfortunately the gold plating on your electrical connectors may be quite thin, only a few molecules deep. Your best bet may be to sell them "as is" to an optimist. Grandpa

Answers:75% gold. Gold is measured in carats, with 24 carat being 99.99% pure. You can work out the gold percentage by calculating carats x 100 / 24
