Dating of (quasi?) autonomous coin from Tyana in Cappadocia

[Altamura]

There is a coin type from Tyana in Cappadocia showing on the obverse a bull walking to right or to left (both variants exist) and on the reverse Zeus seated to the left:

In the older references this type seems to be dated roughly to the first century BC.
The main references for this early dating seem to be SNG Copenhagen 315 and Lindgren I 1733 and 1734 (sometimes you find also Lindgren II 1733), where I don't have access to  .

Since some years this type is dated to "Circa 2nd century AD" or similar.
In RPC online we have it now attributed to Trajan with a reference to Ganschow II, 1002 and 1003 respectively:

Does anybody know where this later attribution comes from and which are the arguments for it?

T. Ganschow, Münzen von Kappadokien. Sammlung Henseler I-II (Istanbul, 2018).

There seems to be no online access

Yes, in the book by Thomas Ganschow it seems to be dated to the time of Trajan.

But why? This is my question.
Did he copy it from elsewhere? Does he give some arguments for this dating?

You already find this late dating in an auction from a time before Ganschow's book appeared (which was in 2018):

Who attributed this type to the time of Trajan and with which arguments???
