NOTE: I am considering creating a different system for tracking, similar to the Carnegie Museum style. It is a simple CM 12345 mark. While it is nice to include the locality, year, month in the specimen, I believe I can keep that information separate in an online database for referencing.

I need to keep order of a growing collection of specimens so I have developed the following identification system to be used on what I call Collection Pieces.

Therefore, an example Identification System code:
CG-0001

Codes shall be deconstructed as follows:
COLLECTIONID-SEQUENCE

Locality codes

LLimestone
ALAmes Limestone
MMid Level Shale
USUpper Shale
KPieces from an Eastern Gilpin Township Locality
GPieces from a Western Gilpin Township Locality
UUnknown Origin

Consequently, identification numbers are to be added directly to specimens. I did research on different methods, in conclusion I found archival ink pens seem to be best in class. White paint appears to work well on really dark specimens.

A Catalog of Pieces

These are some of the early pieces that I have added to my collection, so far.

Identification System Collection Pieces as a Category

You can find the entire category listing here.

Examples of Identification Systems Elsewhere

I did research on identification marking and numbering systems before I developed my own. I wanted to make sure I was not missing anything before I set a standard. Here are some interesting examples in use.
