That there's a mighty expensive coin! I'm afraid I'd hafta sell the house & everything in it to buy that one.
Its getting tougher these days to find bargains. Its still possible if you collect mostly world/ non US AV coins. RRRR coins with less then 3 known are possible in rare cases for under 10 grand. But again, some sell for absurd amts, with many known. The 1839 "Una & the Lion" AV 5 Sovereigns (50+ known) one sold MDC/ Monaco auction 1M EUROS, recently prices dropped a tad. This Regensburg ND 1792 Dukat sold Heritage slabbed MS-63 $24KUS I got this in 2015 for 1900E But, this 1633 K-B Hungary Dukat FDC sold Warsaw auction 2016 in Zloty= $4100US (I won it) Then in 2023 Bratislava Auction a MS ex. not as good as mine, hammered for 26K euros. We would be flabberghasted what our collections are worth in 2026 Dollars, then we could buy a Beverley Hills mansion like Buddy Ebsen/ hillbillies.
I knew that. I am not one that cares about a coins provenance but I would pay a premium to own a Jed Clampett coin.
