Most Expensive Coin You Own Is...?

Love that Chain VT!

This is the most expensive coin I have bought - may not be the most valuable as some I bought longer ago could sell for more nowadays. Cost me 6,000 Irish pounds at the 'Millennial' sale in Dublin in 2000. Plus hammer fees.

It's a double groat (8 pence) of Dublin from the 1467 issue.



P.S. The sale prices realised are on the web and the coin has been on my website since 2000 so it would be pretty easy for anybody with a bit of web and coin knowledge to know how much I paid and when I bought it. In my experience most collectors don't really like to reveal how much they have spent on their coins - unless they are discussing a coup which shows them in a good light. This was by no means a steal in price terms - but there hasn't been another example offered since then so it does look like I made the right call.

WOW... That Antietam sure is a beauty.

There had been, as I recall, only three individual coins I ever paid over $30 for (in exchange rates of the time anyway - in today's rates one of them would be less than that).

One of them - the 1818 ruble - I probably overpaid for ($70), but I really wanted a silver ruble, and all the newer ones were more expensive (at that particular place, which I've since abandoned because their coins were a bit too expensive generally).
I'm still searching for a later silver ruble I can afford, but $70 being something "I can afford" was a fluke of that particular day, so I'm looking for a $20-30 price, which is bordering on impossibility.
No pics, unfortunately.

Second place in figures of what I paid comes the 1699 fourpence at $40; I definitely overpaid for that one, but ever since I've never seen anything remotely similar (again, for any price I can afford, which had somewhat gone downward since then).
No pics either, as far as I know; sorry.

Third place at $30 - and for all I know the one with the highest actual value (I estimate $80, though it's probably less in reality) - is the 1841 large cent. I do have pics of that one, luckily, so they would be the ones you're going to see

I have lots of interesting coins, but sadly my most valuable coin is pretty boring:

Agcoinau, thats a great answer.

I think this may be my best, although chasingtailbar might think otherwise. Its hard to say as I dont really know their worth

Wow. The Trade dollar just puts a lot of modern proof coins to shame!

To be honest, I don't know what is the most valuable coin in my collection. A lot of the coins that I bought a long time ago have risen significantly in value, some in excess of more than 10 - 20 times and unless I sell them all, I do not know.

The top three that comes to mind is this:

1834 commemorative ruble - impaired proof. A small mintage of 15,000 however proof makes it a lot rarer.


1730 ruble - double struck, unfortunately holed and repaired. Doesn't appear very often in the market


1795 2 kopek overstruck over 1773 2 para - 3 kopek. This is a lot rarer than what many think.
