Does anyone collect these ? Novelty bullion

This is something I picked up purely as a trade item as I don't collect novelty items, hopefully somebody likes this sort of thing.
Issued by the " Birmingham mint " the set contains 12 x 1 ounce ingots depicting the royal palaces, they weigh between 31.5g-31.9g each.
Some of the ingots have toning on them which I have tried to show in the pictures, boxed but missing its paperwork unfortunately.
Each ingot is fully hallmarked on the edge.

I am after German states 3 Mark coins from c1901-1918, excluding the Prussia issues which I already have.
I would consider anything unusual or different though.
Personal message me if interested.

That's an interesting set of collectables, pity you won't exchange.

I hate the idea of Royals, that includes their blood money acquired palaces.

Nice shiny silver though......

I'll take them at spot+0.75(oz) [trade value]. If interested, look through the German states section of 'my collection' and see if you need anything - I've not decided what to do with them yet so they aren't listed in swaps (or even fully inputted into numista)
