All four of these circular items appear at right front on these notes. Does anyone know what they are, or what they are supposed to symbolize?
If you can precisely identify the name of these items—or have a lead which you think might be useful—please post a comment, preferably including a URL which links to evidence supporting your identification.
Also, according to the SCWPM, these notes (Pick 120-124) were unadopted designs, but I have a scan of a well-worn 100-metical note with normal serial numbers, indicating actual circulation. So, were they issued, and if so, when, and for how long?
