I'm not sure if I'm a member of the #silvergoldstackers group any more since it's been so long that I've posted but I logged into PeakD a minute ago and saw the latest post by 
I'll start off with the smallest but oldest coin. A 1893 half sovereign weighing almost 4 grams (3.66g gold).
Next up is a 1907 Soveriegn weigning 8g (7.34g gold)
Finally we have a 1913 Sovereign.
I believe the soveriegn coins were worth £1 back when they were minted. Melt value today is around £373 each which is pretty impressive.
Prior to getting this coins I had only been able to afford to stack a bit of silver but these coins make a lovely addition to my collection and I just love holding them in my hand.
Good as gold :-)
