Data base description

The data base has been built on a Excel file.

The first page contains all the information of the coins registered:

The name of every coin is composed by its RIC code plus a sequential number.

        Example:
 

Coins restoring DIVO AUGUSTO with eagle on the reverse are referenced as: 77-001, 77-002...
        .
        .

Coins restoring DIVO TRAIANO with pyre on the reverse will be numbered as: 86-001, 86-002.....
        .
        .
In the case of DIVO ALEXANDRO with a pyre, they will be: 98-001, 98-002.....
 
 

Obverse dies are referenced as follows: the name of the emperor restored (2 char.) plus a sequential number.
Ex.: VE01, VE02......VE50

Reverse dies are named by the motive (Aquila, Pyra) plus a sequential number as follows:
Ex.: A001,A002.....    P001,P002.....
The reverse of the hybrids will be referenced as: IM, VA, PA. Depending on their typology.

Statistical data is automatically calculated when a new coin is included.


Distribution for typologies is also automatically calculated every time we include a new coin 


The estimation of the original dies number is also automatically adjusted with new coins.

Related to the data base, a new software is being developed, it builds the die-link trees and makes an accounting of the coins involved in everyone.

This illustration shows part of the main tree which involves the 81% of the coins registered in the data base. Every line referenced a pair of dies and a coin minted with them. The following line references the same information for a coin linked with the precedent one. 

Ex.: Coin 90-010 links by its obverse(AN06) with the coin 89-031, 90-001 y la 90-043. The last one links with 90-034 and 90-082 by its reverse(P096), etc......
This illustration shows a fragment of the main tree which involves the hybrid coins (78-021 y 78-042) with other 730 coins registered. Some of them are shown in the following picture.
