Kayqubad I hadn't yet taken the throne when this fals was struck — these dates correspond to the reign of his brother Kaykhusraw I (second reign) and possibly the brief rule of Kaykhusraws's successor Kilij Arslan III, a period of sharp dynastic instability in the Sultanate of Rum. Attribution of copper fals from this transitional window remains genuinely contested, and A#1213A reflects ongoing cataloging uncertainty about which sultan's authority actually sanctioned a given issue.
Copper coinage from the Seljuks of Rum was largely a local convenience currency, struck without the precision applied to silver dirhams, and surviving examples vary substantially in fabric and flan quality even within a single type.
