Nothing in the lot that will let you retire, but it's a neat collection of world coins to be sure. Aside from the previously mentioned silver, the UK/Australia large pennies have a bit of a collector base, and are worth ballpark $1-2 each. The rest are just modern world coins and are worth the exchange value; about 1-25 cents each from what I can see.
Total price for the lot, I'd say ballpark $20, with the majority of that being in the silver.
