Just saw them on Numista. Some of these coins are just bonkers but so beautiful.
The top one is a 7 kg (Thats about 15 pounds for our American friends). This coin is 185mm round and has 7kg of pure gold with a melt value of $610,000 NZD or about £315,000, way above its face value of £7k.
https://en.numista.com/catalogue/pieces200037.htmlBefore you want to rush out and buy it (Perhaps you may be Lord Sugar or Her Majesty reading this

) - The total mintage was just 1!
A bit lower down the affordability scale is a 2kg coin with a face value of 2k.
https://en.numista.com/catalogue/pieces200035.htmlYou have a 7 times better chance of getting it, with that many minted and an affordable £129,990 Price tag

Of course you can buy the darn car for less.
More prices - 1kg, 17 coins, £60k
500 pounds - 1kg silver - 70
500 pounds - 5 oz gold unknown but I guess 10 or 15 grand
Anda range of lesser coins and values down to £5 Nickel coins costing about £20 or so.
The top coins only show the car, but others show Martini shaken not stirred and 2 more of the car.
