There’s a committee[0] and I guess Roman coins are one of the easier artifacts to value as there actually are public markets for them[1].
If you, as a finder, disagree with the valuation, you can “send your own valuation for the committee to consider”, which sounds like an interesting process to navigate. I imagine you’d have to find a credible alternative buyer who’d be willing to pay a higher amount.
Yes, I am open to the possibility that confiscation by the state (with compensation) in the interest of national heritage may be the right thing to do in such cases, I'm just, as I said, skeptical of the claim that "full market value" for completely unique things that have never been on the market can be determined by a committee; and that interests of the farmer and the interests of the government are as blissfully aligned as was claimed.
This is a fair comment - price calculation is one of the main services the free market provides and I am also skeptical that a committee can perform that service to the same standard.
