Quote:
what is 'tooled'
In general it is any artificial modification of the coin surface. But one distinguishes three different types of 'tooling':
1. inadvertent changes to the surface during cleaning (with a hard object)
2. intended changes to 'improve' the grade of a coin (eg flattening out rough spots)
3. modification of the coin to create another type
The first is normally excusable as part of conservation, the second is to a degree understandable but can be criminal, the third is definitely criminal with the intention to create a forgery.
Mostly it is an easily noticeable change which lets people emphasise that a coin has been 'tooled', ie types 2 and 3.
