Any variety listed for the missing Y in York? Probably just grease filled. I would say for condition and historical content. They should be atleast worth $10 a piece.
I am not familiar, but hopefully one of our medal specialists will chime in, I did look up the Battle of Thames - which took place in Canada during the War of 1812 - from the interwebs, "The Battle of the Thames, also known as the Battle of Moraviantown, was an American victory in the War of 1812 against Tecumseh's Confederacy and their British allies. It took place on October 5, 1813, in Upper Canada, near Chatham." I like the subject matter / ships and age. Condition is above average. I especially like the reverse of the Thames / Harrison (later President) medal which, like the 3 cent Feuchtwanger (State of NY seal) features a kind of space alien looking character (probably Tecumseh or a Shawnee warrior). Also note, Tecumseh's death in battle, at the Battle of Thames, led to the breakup of the multi-tribe Indian Confederacy army he led and was a significant contributing factor, accordingly, in the eventual loss of the war by their allies, the British. A google search indicates what appears to be a German Silver holed version of this medal sold for $425 by jkamericana so it may have more value than you might think.
The second medal, the William Henry Harrison piece, is a good item, to the right person, is worth some money. It is listed in DeWitt - Sullivan as WHH 1836-1. It was thought to be the only William Henry Harrison piece that was issued for the 1836 presidential election. That year the Whig Party ran three regional candidates, Hugh White from the South, Daniel Webster from the Northeast and Harrison from the West. The idea was to split up the vote so that the election would go to the House of Representatives, where the Whigs hoped to win as they did in 1825. Martin Van Buren won anyway, but Harrison did well enough to capture the Whig nomination in 1840 and eventually win the presidency that year. I have an example of this piece which questions the 1836 date for this piece. It is struck over and 1838 large cent! Of course the medal could have been issued for both elections. Here is my example. If you have Rulau's book on Hard Times tokens, this is the piece to which he referred in a Joe Levine auction.
