"What is an un-circulated coin?"
Uncirculated means a coin has not had any wear,
such as the wear a coin might experience when it is
used in commerce. Handling a coin, as well as improperly
storing a coin, can result in wear on the surface
of the coin. This wear, even if very minor, will
cause a coin to no longer grade uncirculated.
(Uncirculated Coin 不可有花痕, 而有花痕的新幣可以俾降級不可叫 Uncirculated)
What's a proof coin?
A newly minted proof coin is also Un-circulated,
however it is the way it is made that causes a difference in
appearance and qualifies it as a "proof". To understand
this, let's look at how coins are made. Coins are
produced when two dies strike a blank piece of metal
with tremendous force. One die is engraved with the
front (obverse) design for the coin. The other die
has the back (reverse) coin design on it.
