Sales for the Mares of Diomedes 1 oz silver and copper rounds for the exclusive 12 Labors of Hercules series from Provident Metals have concluded, wrapping up their one-month run.
King Eurystheus sent the Greek demi-god to capture the Mares, which were trained by King Diomedes of Thrace to crave human flesh. Hercules killed King Diomedes and bound the mouths of the four fire-breathing stallions closed before easily taking them back to Eurystheus to successfully complete his labor.
Hopefully you successfully seized the Mares of Diomedes as Hercules did, as the rounds have now been discontinued. The final mintage numbers are listed below:
Silver: 6,547
Copper: 5,020
With the Mares secured, Hercules moved on to retrieve the Girdle of Hippolyta for his ninth task, a job given to him by Eurystheus because the King’s daughter desired the belt. Hippolyta is portrayed on the reverse of each 1 oz silver and copper round, which will be available from May 12 through June 12, 2015.
If you’re interested in seeing the 10th design in the 12 Labors of Hercules series, a sketch of the Cattle of Geryon has been released.

I think the mintage numbers now start to go up significantly. The Girdle of Hippolyda looks good and I think it will do as well as the Boar. The Cattle of Geryon will do even better. The numbers will really take off on the final two coins as the Apples of the Hesperides was the most difficult of all labors. That coin could be designed in many different ways so I’m anxious to see it. The final coin should look great as well and it was a very difficult task. I have been adding Augean Stables in bulk to my personal stash. That not only was one of the most difficult tasks, but it also has the least mintage. I think that coin has the potential to be significantly more expensive in the future. Who’s going to want just a few of the labors? You’re going to want them all, right?
Why does the Nemean Lion say “no longer available” and the other ones say “discontinued”? Is there a difference?
Hello Tom, all the products show as discontinued status on our end, both on the product and category pages. Ultimately they’re the same though. Discontinued products are no longer available. Each of the H12 designs are available for only 30 days. Girdle of Hippolyta is the only design available at this time, other than the 5oz and 1 oz proof Hercules designs which are both available through September 12.
The page isn’t displaying the 10th labor – Cattle of Geryon.
We currently have only a sketch available for display. Here is a link to the Cattle of Geryon product, which is also visible on the category page. http://www.providentmetals.com/1-oz-silver-cattle-of-geryon-the-12-labors-of-hercules.html
Thank you for explaining.
