Just try adding 1000 coins to any of the different options and you'll get Bimetallic, Bi-metallic and Bi-Metallic showing up in you metal-list. You just start wondering what other "metals" are hidden in that "other" group (or maybe that is why we don't get to see them?
To correct this, I'd have to go back to the 70-something coins I just corrected and add a capital M to every coinsheet and also go through 2500 of Bi-Metallic/Bi-metallic coins to look up the ones without a capital letter.
Maybe in this case the grouping of metals can be made non-case-sensitive on the dashboard, but is there no way such bulk changes (relace Bi-metallic by Bi-Metallic) can be performed automatically in the database by an administrator (or Xavier) himself? Checking a few pages to make corrections is fine, but 25 is a bit too much ...
