SOME VALUABLE MATERIALS
|
 |
This
is an alloy of copper and tin, usually dark brown with a shiny patina.
Many sculptures have been made of this material throughout the ages. Pieces
range in value from a few dollars to many millions; those from Austria
are particularly valuable. |

U.S.
90% silver coins are dimes, quarters or halves dated 1964 or older. Silver
Dollars were minted up to 1935. I buy all early U.S. coins if they are
not damaged in any way. In general, the better the condition, the higher
the prices. I particularly want to buy gold coins. When a gold coin has
been used as jewelry, it has signicantly less value because the frame nicks
the milled edge. |

Usually
stamped 10K, 14K and 18K. It is bought by the pennyweight (dwt). There
are 18.2 dwt to the avoir oz. or 20 to the troy oz. Dental gold must be
yellow and is always 16K. Items stamped '1/20 12K - H.G.E.' are gold plated
and worth relatively little. I will be happy to test items that look like
gold and are unmarked. If there are diamonds or other precious stones in
the item I will add their value to the weight of the gold. |
 |
Items
must be stamped 'Sterling, .925, .900, .800 or 84 (which is Russian and
often very valuable). Many items stamped 'Sterling' are weighted with plaster
and must be broken to get the true weight. Knives which have sterling handles
are figured at 1/3 to 1/2 oz each. |

Gold
pocket watches made in the last 20 or 30 years are probably worth their
weight in gold only. Hunting case watches (flip covers) that are working
or repairable are valuable. Repeater watches which chime the time are very
valuable - often worth over $1,000. Old silver watches are also worth a
premium. Rolex, Patek Phillippe, Franck Meuller, Bulgari, Van Cleef &
Arpels are just a few of the world's most valuable examples. |
