Hello all

I'm a hobbyist silversmith, only making items that fall within the exemption weights for sale.

However, for work, I am making a silver "trophy" which is going to be a little heavier than the exemption weight.

My question is, does the item still need hallmarking if it technically isn't being sold? It's a prize, so in theory the winner has paid for it through hard work, but no cash is exchanging hands.
