Creating A Register For Collectable Coins

It's a good idea in theory. But there are three big problems to this.

1) Coins change hands frequently, most often without an official receipt of sale of sale. How would anyone keep track of all this, even of it was law to record it there would still be a large amount of discrepancies.

2) Coins change over time. A coin changes over time in apperance. Coins wear, tone and are (unfortunately) tampered with. A coin made now will not look the same in 10 years unless it is kept in an airtite, dry environment.

3) The biggest problem, there are too many of them! The vast majority of people aren't collectors and don't know how to deal with a rare coin even if they had one. An undertaking would require a massive backing and even then, there will be issues.

No, the best way, is to either learn to properly identify a coin (Which I recommend despite whether you chose option 2 or not) and buy from reputable sellers. Or Option 2 which is to always buy graded coins (PCGS, NGC, ANACS, ICG).
