Greece 5 lepta 1878-K: missing privy mark

Just got 3 feet (yes, feet) of fresh snow today - and I thought winter was just about over - ugh!

Anyway, the coin in question is this one:

N#4088

The 1878 dated coin in this series was minted in Bordeaux, France and has the “K” mintmark.

As such, it also has the Engraver-General's privy mark (anchor without bar) and the Mint Director's privy mark (a cross with the ends of the arms as points or arrowheads); not sure what the correct name is for this symbol, so I will stick with “cross”. The photo of the 1878-K coin in the valuation table clearly shows what this privy mark looks like.

The Numista webpage for this coin series lists all of the possible privy marks for the coins in the series except for this “cross”. It is missing from the “Marks” section (where the other privy marks are listed and identified) and also in the valuation table for the 1878-K coin.

Since my computer skills are very poor, I don't know how to get the “cross” privy mark added to this page. If it could be added by someone who knows how to do it, that would be great.

One other question concerning this coin (and several other Greek coins from the 1800s): The SCWC lists the alloy for these coins as “copper”, but Numista lists the alloy as “bronze.” Is this one of the many SCWC errors that has been corrected in the Numista catalog?

No CROSS privy mark, or otherwise, is specified in KM's SCWC 1800's (KM#54), I'll check others and get back. Also, KM says copper and I favor copper just based on the color, admittedly not the best measure.

The SCWC does not show the privy marks used by the various French mints; you have to go to the “France” section of the SCWC to see them.

I very much like how Numista shows the French Mint privy marks on its web pages for non-French coins that have them - that saves time having to look them up on (presumably) under “France” over and over. 

The “cross” privy mark is shown for the 1878-K Greek 10 lepta coin

but for some reason it is not mentioned/shown for the 5 lepta coin under discussion here.

The easiest way to fix this would be to make the privy mark section for the 5 lepta coins under discussion here look like the privy mark section for the 10 lepta coins mentioned above - the dates and mintmarks are the same for both coin series.

The entry for the 1878-K 5 lepta coin on its webpage would also need to have the “cross” privy mark added.

I can make simple changes to correct errors on coin pages, but I do not know how to make these particular, more complex changes.
