OK, let's see what we've got here. Without pictures, I can only assume the coins are "typical condition". Note that prices here are catalogue prices - that is, what you'd expect to pay if you bought one off eBay or a coin dealer. If you went in to a dealer's shop to sell them you'd be lucky to get half that. May not seem fair, but the dealer's got a family to feed, too.
Australian values from the Pocket Guide, foreign values from the Krause catalogue (it's American, so those prices are in US dollars)
Coin 1: Australia 1 penny 1958. CV (Catalogue value) $1 in Very Fine. Note there are two varieties to look for, though they're worth the dame: the Perth mint variety has a dot or full-stop after the word "penny", Melbourne mint has no dot.
Coin 2: Great Britain ½ penny 1897. CV 75c in Fine. It's actually a picture of Britannia (a female) holding a trident there.
Coin 3: Great Britain 1 penny 1930. CV $1 in Very Fine. Pity it's not Australian - you've probably heard about the extremely rare "1930 penny"? This, sadly, isn't one of them.
Coin 4: Australia 1 penny 1957. CV $1 in Very Fine.
Now for the shillings: All the Australian ones are made of silver, so with the silver price "going great guns" they're not worthless. The Pocket Guide dates from last September's silver prices, so may be obsolete by now.
But here's what it says:
Australia 1 shilling 1952 and 1954: CV for both is $3.50 in Very Fine.
The British shillings dated after 1946 are not silver, but cupronickel (like our 10c coin) and aren't going to be valuable unless they're uncirculated. It's at least worth 10c from a vending machine! [:p]
Also note that from 1937 there were two different designs on British shillings: the "English type" and the "Scottish type". For George VI, the English type has lion standing sideways on a crown, the Scottish type has a lion sitting on a crown holding two sticks (actually a sword and sceptre). For Queen Elizabeth, the designs changed to English: three lions on shield and Scottish: one lion on shield
Not that there's usually very much difference in value - the British made so many coins that there aren't to many "rare ones".
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
