There were 1 Rand and 2 Rand coins minted in gold in 1975, and some were produced for proof sets.
South Africa in 1975 sold three different proof sets: an 8-coin set (1/2 cent, 1 cent, 2 cents, 5 cents, 10 cents, 20 cents, 50 cent and 1 rand [silver]); a 2-coin set (the two gold coins); and a 10-coin set (all of the above).
I would suggest looking on eBay (the KM numbers are KM#63 for the 1 Rand and KM#64 for the 2 Rand).
There were 2,000 of the 9-piece South African proof sets produced in 1951. They are valued (according to the 2010 Standard Catalog of World Coins) at $80.00 per set.
It should be noted that the "rarest" coin is not necessarily the same thing as the "most valuable" coin. The New Zealand 1935 Crown (Five Shillings)(Waitangi) is New Zealands rarest coin and possibly the most valuable general circulation coin, in this case. There were 660 general circulation coins minted and 468 Proof coins minted. There are quite a few New Zealand coins with various minting errors and other little peculiarities, but known quantities of these usually number in the thousands.
There were proof sets made in 1974 and 1975 where all 8 of the coins were silver, and proof sets made during those years when none of them were silver. Assuming that your coins are in a set, check the 1 Cent coin - if it looks silver, then all the coins in the set are silver; if it looks bronze, then none of the coins in the set are silver.
A New Zealand 2006 50 cent coin, uncirculated and in absolute mint condition could fetch up to $2 NZD. There were 70.2 million minted. A reputable coin dealer will be able to give a more accurate valuation. These coins are still in circulation so, unless they are part of a Proof or uncirculated mint set or are individual Proof or uncirculated coins and in absolute mint condition, they are worth 50 cents.
The New Zealand 1 and 2 cent coins were progressively withdrawn from circulation from 1988 and demonetised in 1990. So, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they have little or no collector value. The Reserve Bank of New Zealand will pay face value for legally issued New Zealand currency. See the link below.
Such a coin does not exist. The only British Half-Sovereign coins minted in 1923 were minted at the Pretoria Mint in South Africa and were all Proof coins.
Current circulating U.S. coins are minted in Philadelphia and Denver, with collector proof coins minted in San Francisco.
No these are proof coins, but some proof coins do show up in pocket change..
No. There were no Proof Halfcrown coins minted from 1840 to 1849 inclusive.
There were 2,000 of the 9-piece South African proof sets produced in 1951. They are valued (according to the 2010 Standard Catalog of World Coins) at $80.00 per set.
There were no British 1998 10 Pence coins minted for circulation. There were some minted for Proof and Mint uncirculated coin sets.
There were 1,000 1988 Isle of Man Proof gold "One Angel" coins minted.
None. There were 2,015 Isle of Man 1986 platinum Quarter Noble one fourth ounce Proof coins minted. There were 3,000 Isle of Man 1986 platinum Noble one ounce Proof coins minted.
For coins minted in British India (pre-1947), the Bombay minted used a dot. For coins minted in independent India, (post-1947), the Bombay mint uses a small diamond (although proof coins from 1969 to 1995 used a "B").
Philadelphia, Denver, San Francisco (proof only)
Before 1965, all proof coins were made in Philadelphia. In 1965 production of Special Mint Sets was started at San Francisco. In 1968 SMS production was ended and proof coinage was resumed, but it has remained at San Francisco ever since.
For the year 1900 a total of 66,831,502 business strikes were minted & 2,262 proof coins were struck.
