Guidelines as to when it's appropriate to split/combine coin pages?

6 posts
As title says.

Is there any guideline or policy as to when it's appropriate to split or combine similar coin pages? At the moment my own policy is to split when different metals, or metal purity is used, but to have multiple similar coins (especially if they're just essais, etc.) on the same page otherwise.

Should KM#s be taken into account in any way?
We are slowly putting together new guidelines, but there is no document published yet.

Reasons for new page:
  • Different metal purity
  • Different metal (unless the difference is very tiny and cannot be noticed by normal means (weight/color)
  • Different measurements - for example Piedforts
  • Different usage (pattern/essai)
  • Big lettering difference/Big design difference (obvious in modern, but old coins have usually a lot of different coins under one KM)
  • Different denomination

These are proposed guidelines. World coins vary greatly, so I dont know if there will be any problems with these rules. If you see some, let me know.

Reasons for not splitting the coins:
  • Different ruler if the coin design is same
  • Different KM when coin is the same (ie. when Krause is wrong) (This applies to any catalogue)
  • Tiny metal variation (see above)
  • Slight design changes

The above implies that there can be both coins with two KM numbers and two (or more) coins with the same KM number.

OK, thank you.
Nowadays, proof versions of a coin are considered just another kind of Year, why not keep this logic with essai/pattern and piedforts ?
Lets adopt the KISS philosophy, "Keep It Simple Sucker"
Because essais and patterns often have additional wording. Piedforts have different weights and measures. You will completely screw up the data for weights and measures on your coin collection data page.

​Yes, indeed.
