How can I Delete Coin Entries?

Just wanting to know how to delete coin entries that aredoubled or tripled?
Many Thanks

You can give,quote here the sheets .
A member of the team will delete doubled or tripled.

Is anyone allowed to add to this Topic ? I show below one that may be duplicated. Please check first though, in case I made a mistake, and I believe you have to also amend collections if the second entry is a duplication ?!

 Duplication ? 10 Euros Marathon  2007  Portugal  KM#?

Thanks :)

P.S. I wondered whether the last three of these four below should be deleted - the first one says 2002-2009 and the others start at 2003 2005 2007 dates, so would be included in the first entry ? Not having photographs or KM numbers to go by though. Also all four entries may have been created at around the same time (but by different people), having close page numbers to each other. Though if it was one person I cannot see why there are four entries. It is the Australia 1 dollar kookaburra.

 I remember reading in the Topic below that the system would alert a member from adding an existing KM number, but as those six I mentioned above do not have one when entered, then these sort of possible duplicates do happen.

It's made
Thanks for your participation.

https://en.numista.com/catalogue/pieces21182.html This is NOT a maundy issue coin, it is the circulation version. Someone has changed the currency from sterling to maundy and then locked it making it incorrect - i created the coin correctly. It needs to be changed back.
