Hi again, Richard. These are actually repairs to the die rather than a true double striking. Most conspicuous is the linear circle repair around REG - the new circle touches the tops of the letters whilst the vestiges of the original circle above the letters can still be seen. Similarly, just before BRITT the new linear circle isn't actually circular, but rather undercuts what's left of the original. Interesting, yes, but of no huge significance - die repairs in the early years of the Viccy bronze series are rampant! Looks like the R in REG would be the next letter due a repair! A true double striking would see consistent duplication rather than scattergun.
