The present roster of coin entry forms is not exhaustive but should suffice for most major collector types and periods. Consider using another form that most closely matches the needs for your particular coin based on the available fields.
The development of Tantalus is ongoing and expanding the layouts is an important goal of the agenda. Please feel free to send us a note at tantalus-help@tantaluscoins.com if you have a need for a specific coin type not yet represented.
