Series E sceattas — the so-called "porcupine" type — are among the most prolific early medieval silver coins found across the North Sea trading zone, almost certainly struck in Frisia as commercial coinage for the emporium economy connecting Dorestad, Hamwic, and the Frankish Rhine ports. The TOTII variety sits within a complex classification built largely by Metcalf and Op den Velde, whose die studies revealed that production was decentralized, likely across multiple workshops rather than a single controlled mint.
The "var. A" designation reflects specific pellet and annulet arrangements used to distinguish die groupings — not a meaningful hierarchy of rarity, just taxonomy.
