The Rarest Of The Rare What Is It

Typical of European auctions houses to set a very high opening bid. A scam IMO.

Continuing to venture beyond American coins, here is a coin listed as UNIQUE in a 1963 catalog (Delmonte "Le Benelux d'Or"), but the second known example sold recently for a paltry 9500 euros.

Some folks spend more than that on a bottle of wine.

Stumbled across this one recently: https://en.numista.com/catalogue/pieces445280.html

The example in the photos has sold three times over the last 15 years. No other examples have come to market as far as I can tell.
But I would be curious if anyone else can find one.

Here is another European coin, the second known example, a steal at $6500 or so.

There is also a lot of history in that coin. 1581 was the year the Dutch Republic was formed, yet the coin was struck under the authority of Philip of Spain, making it a "last gasp" coin of Spanish authority over the northern Low Countries.
Imagine a George III coin struck in an American mint in 1776, and only two examples were known. I can only imagine what kind of price such a coin would fetch.
