Hello, Jeff --
Most of Hitler's Third Reich coins with a swastika carry some, but not much, numismatic value. The 1936A coin in our picture is from Munzenversand Udo Helmig and is in good shape numismatically (that is, from a coin collector's point of view). Helmig's selling price of 120 Euros shows how a rare date and a great condition can pay off in coin value. If you had a coin like this to sell, a dealer would likely pay about one-half the retail price.
Don't use metal polish to remove the spots, Meutia. That will ruin the value of your cool British coin. Be sure to handle your coin by its edges only. No fingerprints allowed!
It sounds like you have a gold sovereign from 1914. It could be a half sovereign, because the two coins look alike, only their size is different:
HALF SOVEREIGN: 19 mm diameter, 0.118 troy ounces gold
SOVEREIGN: 22 mm diameter, 0.235 troy ounces gold
Those are two patus, a weapon and pounding club used by the MÄori, the indigenous people of New Zealand, on the reverse side of this three pence coin. The obverse, or 'heads' side, has the British ruling monarch, since New Zealand is a parliamentary state of Great Britain.
These coins were minted in 50% pure silver between 1933 and 1946. After that it was non-precious copper-nickel.
The coin in our picture is in beautiful uncirculated condition, and CoinQuest thanks SivesaCoins, a respected eBay seller, for use of the photo. It's a beauty!
That is a blue crane on the back of these neat coins from South Africa. The pattern on the front changes on some coins, but the back with the blue crane stays the same. All of these coins are modern and made of non-precious metal. The value is low:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: $1 fully uncirculated: $2
Wow, Jason. It would be something if you have a genuine Continental Currency piece. These are worth tons of money. Our picture, of coure, is a replica, worth essentially zero. Note the word COPY tucked neatly away in one of the circles on the reverse.
NEVER CLEAN A COIN. CLEANING RUINS VALUE.
Here is what the Red Book, the definitive US coin catalog, says about your coin:
worn: $7,000 US dollars catalog value
average circulated: $21,000
Australia issued these coppers from 1911 to 1939. After that, kangaroos appear on the back of penny and half penny coins.
Most of the pre-39 pennies and half pennies are low in value. Below is a list of approximate catalog values for just about all the dates in the penny and half penny series. Special *better date* coins appear on this page after the common date values.
