There are four questions you should answer when determining whether to add a
coin to your collection:
- Is the coin appealing to look at?
- Appeal can be different for each collector. If the coin doesn't appeal to you, don't buy it.
- How lustrous is it?
- There is no way to restore a coin's luster—the shininess of a new coin—once it's gone.
- Is it damaged?
bag marks, staple marks, corrosion and other damage will decrease a coin's value.
- How worn is it?
- According to experts, wear tends to be the single biggest factor that determines the
grade given to a coin.
