First things first from a collecting point of view, Caveat Emptor? Or should one of these medals be confirmed would it be more valuable due to its rarety than an `genuine` one? From a moral point of view, I think that once it was ascertained that the medal had been issued dare I say by mistake then it should be withdrawn until such time that the correct time period had been achieved? I don't believe the Chief of the force(s) in question could be held to account as he/she just signs them off in bulk I would have thought, but certainly questions need to be asked on the administaration departs within the force(s) in question. Lastly I don't believe for one minute that the Royal Mint had a new staff memeber who didn't know the criteria, there is certainly something fishy going on there!! I would suggest that the Royal Mint simply produce the medals they have been requested to produce and have no say or question any of these medals. Further more I am very surprised that this error having come to light has simply been allowed to pass with no follow up or reclaim of the medals in question. I personally think that it devalues the whole medal process and beggars the question, if this is the case then why bother having a long service medal at all. If this had related to campaign medals, would the awardee have been allowed to keep it, I strongly suggest not!
