As the (possible) inspiration for this idea, I am happy to be the first to endorse it. I wonder if you can ask our friends in the pouring community for ideas on how you might be able to 'preserve' a half melted version of the smaller coin on the front face of the bar.
Perhaps after pouring it into the mold, with the blowtorch still on full, wait for the silver to cool just enough to support the weight of the fractional coin being sat on and sinking a little into the bar. Then torch it to slightly melt the wicked witch of the west?
thats a cool idea id like to see if it can be done!
I will own it I will burn it
i hope the royal mint see the melting video :) it will be a big finger up to them
have some ideas wait till you see
