This example appears normal but on closer examination, there are a several details that put its genuineness in doubt. T

he gilding metal is quite flimsy, of poor quality and easy to bend unlike usual York and Lancaster badges which are made of stronger gilding metal. 

The slider is unusually long and fixed to the top of the Coronet whereas it is normally fixed lower down.  The detail in the stamping to the rear of the badge is poorly defined and not as ‘crisp’ as what would usually be expected of a genuine badge.
