If you read the footnote in RIC VII for this coin you would know why I would buy it in a heartbeat at 25 euros. (But, I have #40 and the mate to this, #50, so for me it fills a gap.) But, I digress. The footnote points out that this has a distinctive obverse legend not typical for this series. Moreover, though he rates it as scarce in the museum collection survey, all the other coins in this VOT XX series (see standard) are rare.
If you decide not to go for it, please let me know where you found it. There is a seller on Vcoins offering one I don't like as much for US$125.
