Expensive coins..due diligence etc

[Ansel]

Good afternoon all,

I have been considering diversifying my gold stack which is currently mainly bullion in the form of sovereigns and a few one ounce coins. I do have some Vicky shields, a 2017 proof and a 2017 SOTD. I have now come to the point where I would like to buy something really nice that will hold it's value over the next ten to twenty years and will be a highlight in my collection. I am thinking a graded, mint state, 1817 sovereign. Long term I would like to add a 1989 and a 1937 too.

Can anyone, or hopefully many, offer any advice of where I can find details of the sort of prices I would be looking at? I have been looking at eBay, various dealer's websites and www.londoncoins.co.uk. thus far. I have to say this is somewhat out of my comfort zone currently so any other advice would be very welcome indeed. 

 

Thanks in advance.

Great idea @Ansel, I am on the same path myself with half sovs. I have the 1989 and 1937 and aim to get an MS 1817 half next year.

@shawy2510 @Sovereign @Elements should be able to help with grades/prices.

I have done similar recently tracking prices of a MS graded 1817 sovereign

I used coin archives and also realised prices from auctions at heritage, london coins, balwins and eBay etc. see below!

Google searching helped too

06/09/2019	4560 USD
06/09/2019					2400 USD
14/08/2019				3120 USD
30/06/2019		£  3,800.00

my source of price info is pretty much the same as @h103efa has shown. Using those together gives a good estimate
