How to interpret the score of P box rating currency?

AU is an ABOUT nearly circulating. Among them, 58.55 belongs to the excellent near -circulation, and it is already quite good to be able to reach this score. MS is the coin of Mint State, that is, the factory state. In fact, sometimes we look at the coins of many P box's MS scores. There are also some scratches on the currency. Although these coins have not been circulated, contact with foreign bodies will produce scratches and moisture contact with moisture contact. It will produce oxidation, so MS has 11 levels of 60 ~ 70 in the subdivision, but usually the highest is 68 points, and the 67 points are rare.
The expansion information:
For the standard of rating, PCGS mainly follows the following aspects: 1. Traces, MS allows multiple hair traces, and slight wear machines will be AU. The identification of the contour of the currency surface is about to be XF. If the currency surface pattern is below 60%, it is reduced to VF
2. Pressure. If it is not circulating between intact and complete, if it is weak, it will be reduced to XF
3. The gloss should bring the original light when the factory is out of the factory, that is, the wheel light is too poor, and the AU level will be downgraded. The original light will be incomplete. The original light of 58 points will generally be more than 50%. There will be a little raw light in the XF level, but the interrupt is more serious or difficult to identify.
4. Visual sense, this is also the most important. Often, everyone said not to just look at the scores. It depends on the state may mean it. MS needs to be perfect. AU is at least good. Keep the original state as much as possible. Often some old paste can cover some flaws of the coins, such as scratches, and some colorful bags and even the price are several times higher than the same score. So most of its final score will be 55 points.
