The Japanese 10 Yen from '51 thru '00 is 4.5 grams of 95% Cu.

Heh heh... the Great Britain copper twopence "cartwheel" contained between 56 and 58 grams of copper. And it was 5mm thick:
Now THAT'S some copper!

Canadian Pennies to 1996 are 98% pure copper - so much more pure then US 95% Copper Pennies. You can buy them here by the pound at You must be logged in to see this link.
"The Japanese 10 Yen from '51 thru '00 is 4.5 grams of 95% Cu." Given the approximate exchange rate of 1 yen to the penny, these are not worth 10 cents of copper (yet).
Mexico has some nice obsolete large copper coins too. |

There are plenty of nice big coppers from around the world. Today I dug through a dealer's "junk box" with all his world coins that he was selling for ten cents a coin. I didn't see anything that I was sure had over ten cents of copper in it, but I noticed there were a lot of coppers in there of various sizes.
I will help you with British coins if you have any, and whatever other countries I might be able to figure out by using the World Coin reference books. And I am sure there are others that will chime in like JadeDragon & Bluegill have...
So what else you have? |

If you have, or are interested in Mexican Cu coins, this might help.
You must be logged in to see this link.
Pre decimal UK and a lot of her Dominion's pennies are 9.4 grams of Cu. I have seen conflicting info as to whether they are 95% or 97%, or 97.5% with the Aussie coins. The half pennies are 5.7 grams. The decimal UK Cu coins are 97%.
Irish pennies (and half pennies) share the same specifications as the UK coins. Both pre and post decimal.

GREAT BRITAIN COPPER
PREDECIMAL PURE COPPER COINS
1806-1808 penny...... 18.9 grams
1825-1860 penny...... 18.8 grams
1806-1860 halfpenny.. 9.1-9.5 grams
1806-1860 farthing... 4.5-4.9 grams
Note: 1860 was a major "transition year." Coins minted 1860 and before were pure copper, much larger, and are going to have a HEFTY numismatic premium over their intrinsic copper value. They are also absolutely beautiful!
PREDECIMAL BRONZE COINS - 95% copper unless noted
1860-1940 penny...... 9.4 grams
1944-1945 penny...... 9.4 grams - note: 97% copper
1945-1954 penny...... 9.4 grams
1961-1967 penny...... 9.4 grams - note: 97% copper
1860-1901 halfpenny.. 5.5-5.8 grams
1902-1967 halfpenny.. 5.7 grams
1860-1901 farthing... 2.8-3.0 grams
1902-1956 farthing... 2.7-2.9 grams
DECIMAL BRONZE COINS
1971-1991 twopence... 7.1 grams, bronze (not sure percentages)
1971-1991 penny...... 3.6 grams, bronze
1971-1984 halfpenny.. 1.8 grams, bronze (discontinued in 1984)
TRANSITION YEAR
1992 pennies and twopence issued in collector sets are bronze, but circulation strikes from this year are copper plated steel.
DECIMAL STEEL COINS
1992-2009 twopence... 7.1 grams, copper plated steel
1992-2009 penny...... 3.6 grams, copper plated steel
For the sake of simplicity, some of the minor composition changes (95.5% copper for some years instead of 95%) have been omitted... |

An easier way to think of it is this:
British Large Penney (pre-68): 1/3rd oz
British Half Penny(pre-68): 1/5th oz
British One Penny (1971-1991): 1/8th oz
British Two Pence (1971-1991): 1/4th oz
(Regular ounces, not troy) |

| Most every nation has, at some point in their history, issued copper-based (95% and up) coinage. However, very few nations still mint copper or bronze coins; the practice of which was phased out over the last quarter century. |

Good idea. I like it this way much better.
1806-1860 penny......... 2/3 oz
1806-1860 halfpenny..... 1/3 oz
1860-1967 penny......... 1/3 oz
1971-1991 decimal 2p.... 1/4 oz
1860-1967 halfpenny..... 1/5 oz
1806-1860 farthing...... 1/6 oz
1971-1991 decimal 1p.... 1/8 oz
1860-1956 farthing...... 1/10 oz
1971-1984 decimal .5p... 1/16 oz
So 256 of the decimal halfpennies would be a pound. The problem with that is their unit of currency IS a pound. Hmmm...

From Wiki:
The pound sterling is the world's oldest currency still in use.
Main article: Anglo-Saxon pound
The origins of sterling lie in the reign of King Offa of Mercia, who introduced the silver penny. It copied the denarius of the new currency system of Charlemagne's Frankish Empire. As in the Carolingian system, 240 pennies weighed 1 pound (corresponding to Charlemagne's libra), with the shilling corresponding to Charlemagne's solidus and equal to 12d. At the time of the penny's introduction, it weighed 22.5 troy grains of fine silver (30 tower grains; about 1.5 g, indicating that the Mercian pound weighed 5,400 troy grains (the Mercian pound became the basis of the tower pound, which weighed 5,400 troy grains, equivalent to 7,200 tower grains). At this time, the name sterling had yet to be acquired. The penny swiftly spread throughout the other Anglo-Saxon kingdoms and became the standard coin of what was to become England.

Scandanavia still makes bronze coins!
Norway's 50 ore coin has been produced since 1996. It weighs 3.6 grams, and is 97% copper. At current exchange rates and base metal prices, it's metal value is worth 31% of face value.
Sweden's 50 ore coin has been produced since 1992. It weighs 3.7 grams, and is 97% copper. At current exchange rates and base metal prices, it's metal value is worth 32% of face value.
Denmark's 50 ore coin has been produced since 1992. It weighs 4.3 grams. At current exchange rates and base metal prices, it's metal value is worth 37% of face value. (If you can find them, Denmark's 25 ore coins from 1990-2008 are bronze, too.)
(I should point out that these coins cost 7 to 11 US cents each at current exchange rates.)
These all are good coins to keep an eye on. They might become worth it if copper prices rise quickly, before these nations have time to reel in these coins. Note that each of these coins is currently the smallest valued coin for their respective nations. |

It looks like Sweden might be the first.

| Also, all the one and two cent coins from Australia and New Zealand are 97% because they simply stopped making them rather than switch to zinc. |
