Contact with the author

If you wish to contact the author to contribute with information, photos, make some corrections, sugestions or have doubts, etc.., you could reach him at the following address: icon .

NOTE: Due to the volume of information that is processed to update the website and time constrains, the answer of the emails is not guaranteed to be promptly. This is a research website which does not trade numismatic pieces so it's difficult to the author to make a valuation.

Photo contribution

If you wish to contribute with a photograph for reference purpose, you can send it by email at the address shown before.

The preferred file format is JPEG (or PNG) with low compression, and high resolution. Generally it's not easy to photograph coins minted with other metal than silver or have a Proof or shiny surface.

Some guide for the photographs are:
  • Scanned image (preferred): Resolution of 200-300 DPI (or more). This method is the best for banknotes and most cases of coins.
  • Digital Photo: Resolution of 1024 pixels of width that may be taken using a 3 Megapixels or more digital camera. This method is not recommended because the piece shape is generally distorted, the brightness is not uniform, and the flash may washout the colour.

This requirement helps this website to show as possible the best quality photo reference.

Other contribution

New piece reports

To report new pieces that starts circulation or unlisted pieces (mostly banknote specimen), you can send the report to the email address, along with a photograph of the obverse and reverse (if possible) following the same instructions as the photographic contributions guidelines if possible.

Expand the known banknote serial number interval

To improve the information about known banknote serial number interval, you can send the report by email, and include a photograph of the obverse only, which can be partial showing the serial number and date. If there are more than one reports, you may send all as one image, taking care that the date and serie can be read.
