Okay, I just wanted to write a long detailed description, and accidentally deleted it while trying to copy (and couldn't find an Undo button... you really need to add one). So this will be short

(this smiley exactly describes what I just did when I realized I deleted the post, except that the wall probably wasn't actually made of bricks).
So this will be reasonably short (if I missed any details, please ask).
Oh, and yes, I've bought them because they looked old... it was too dark to see them properly when I made the purchase, and I only realized how awfully badly preserved they are when I got home and looked at them under some decent light. Yes, I know I probably did that completely wrong

Coin #1. Side one: digits "49" near the edge (probably date or part of it); legend before them says <...>OL[ER?]TIA.VINCIT; some kind of design in the middle, with a square right over the center pointing a corner to the 49. Side two: nothing that I can see.
Coin #2. Side one: crowned letter W taking up most of the diameter in the middle, and what looks like digits "18" to the left of it. Side two: some vertical design, possibly a crowned coat of arms (but the arms, if any, are gone - only the vague shape is still there), and what looks a little like the letter O to what would've been the right of it if it's really a crowned coat of arms (which would give the coin the so-called "coin" alignment).
Oh, almost forgot: they're 21mm and 22mm respectively.
Question: what these coins actually are (if it can be told with any degree of certainty), and would they be worth anywhere near the $2.5 combined I paid for them?
