In looking for articles on the Coligny Calendar, I came across some references to "sickle money" about the use of Bronze Age sickles as money (with marks on the blades). I'd like to find images of these sickles to see if they could possibly be Ogham. Here's links to sites that have books/discussions of interest on the topic (a cheap book on the subject sells for $395): http://vml-verlag.de/d/inhalt.php?ISBN=978-3-89646-727-0 http://tinyurl.com/3na4qu http://data.numismatics.org/cgi-bin/libsearch?format=default&fld=any&kw=primitive http://tinyurl.com/4ahjmo Maybe "sickle money" was a calibration scale on a Druid's sickle?
