Hi there. Both coins are dated 1914, the first year they were minted. It is unfortunately the most common date, and among the least valuable. However, they do still command a premium over the silver value - each piece contains around 0.77 OZ ASW, putting the melt value at around $46 ish for the pair at todays lower silver price. However, market value for the pair would be around $140 - 160, somewhere liek eBay.
Hope that helps a bit. Jeff
