All the coins shown in the photo's do have the heads of state on the reverse side as you mentioned but I thought I would show you the interesting sides, also I thought I'd mention the coins are legal tender in their own countries but obviously you won't pop off too the shop and spend them, as they are worth alot more than their face value.
I did hear of a young lad once getting a gold sovereign in his change from a visit to the shop,

And that tin of coins are well worth checking if you still have them, maybe some of them are worth something you could buy yourself some nice new fancy models with the money.
