How you can help the site

- Confirm the existence of a year of issue by sending me scans of coins from your collection, with the size of the image of each side not less than 500x500 pixels
- Complete information about the specifications of coins, mints, names of the designers, etc.
- Find misprints, inaccuracies in the translation
- Place a link to this site on other sites with similar subjects

Sources of information for the site

- The unique content of this site are the large images, self-measured specifications (diameter, thickness, weight) and descriptions of the coins' sides
- Specifications of coins that I couldn't measure myself have been temporarily taken from other catalogs; later they will be replaced with self-measured
- Minor images to represent the comparative sizes of the coins are also sometimes (if I didn't have any coin of a type) temporarily taken from other websites; later they will be replaced with my own
- Information on the mintages, metals, mints, names of designers and periods of circulation is taken from official sources, or, in their absence, from other catalogs (and I prefered national catalogs, if available)

Types of coins

Taken into account:
- Coins of non-precious metals, which were intended for circulation and really circulated
- Silver coins, which were intended for circulation and really circulated

Not taken into account:
- Golden coins: I do not have an opportunity to buy, measure and scan them; besides, almost all of them have very small mintages and could not become a substantial part of the circulating currency
- Coins issued only for sets: due to difficulties with the acquisition of coin sets of the described countries
- Commemorative coin-like products not intended for real circulation, even if a small number of them occasionally appeared there
- Local and private issues (coin-like tokens of leprosariums, etc.)
- Trial coins

Principles of description

- the existence of each year of issue of every coin, and each variety of each year, must be confirmed at least with an image
- all sizes of coins, where it was possible, I measured myself
- most of the sizes are given not as a single number, but as a range of numbers: largest and smallest diameter, thickness or weight of all the available coins of this type (according to the classification by Krause and Schoen); the more coins I could measure, the more accurate is the data
- if I had a national catalog of coins of a country, I gave priority to the information from there (for example, the mintages)
- I call the obverse that side of a coin at which people look first to determine its nominal value; usually this is the side where the denomination is written in digits or, in their absence, in words
- die varieties, i.e. differences in small details were not taken into account; only the most significant varieties of coins were described (for example, by the presence or absence of a mint mark)

Presentation of material

- Coins are systematized not by type, as it is usually made in catalogs, but by years of issue. All the years are shown in a single table. When there are several varieties of the same denomination and year, they are not shown in the tables
- Detailed description of the coins and their varieties is provided on the pages covering all known coins of a country in a decade
- The pictures with the comparative sizes of coins almost never show changes in designs; only important changes in size and metal are taken into account (precious - non-precious and yellow - reddish - silver white - aluminum white); and if it's possible, they show the images of the first coins of this size and color
- To describe the sides of a coin I used standard expressions ("denomination in digits", "denomination in words", "name of the country", "coat of arms", "year of issue", etc.) That reduces the size of the description and simplifies its translation into other languages​​. Anything that can not be described with typical expressions, is described in more detail, including all the translations of inscriptions. Graphical design is usually not described at all, unless it consists of separate, easily distinguishable, not abstract elements.
- For each coin I provided the catalog number from Krause's and Schoen's catalogs. But since these numbers are absolutely not informative, I gave each coin its own number in the following format:

1) country (code according to ISO 3166-1)
2) year of issue
3) denomination
4) number among the coins of this denomination and year

Letters used for the denominations:

A   --   1/4 of a hundredth part of a currency unit (as well as for Jamaica - 1/4 penny)
B   --   1/2 of a hundredth part of a currency unit (as well as for Jamaica - 1/2 penny)
C   --   1/100 of a currency unit (as well as for Jamaica - 1 penny)
D   --   2/100 of a currency unit
E   --   3/100 of a currency unit
F   --   5/100 of a currency unit
G   --   10/100 of a currency unit
H   --   15/100 of a currency unit
I   --   20/100 of a currency unit
J   --   25/100 of a currency unit
K   --   50/100 of a currency unit
L   --   1 currency unit
M   --   2 currency units
N   --   3 currency units
O   --   5 currency units
