I would agree with your identification of the coin type. I didn’t find any match for it on acsearch.info though. The closest was an example of RPC IV.2 913 which recently sold for 50 euros at auction (Demos, auction 60, lot 584). Based on that single result, the relative number of specimens listed in RPC, and the condition of your coin, I might hazard a guess of 100-150 euros for your coin. I’m not an expert on valuation though.
