Czech coin website - amazing

I was playing with the www.searchme.com search filter today and I stumbled on this website. Being a fan of sede vacante issues I thought I had died and gone to heaven. The website had a huge 10,000+ coin collection indexed and imaged. You can search by province, ruler, etc. The only part that troubles me is the collectors mark in dark ink on almost EVERY coin. Ouch. As a US collector I just can't get past that practice. Link to Czech website
From the website:
Welcome to web site of numismatic collection of the state chateau - Archbishop chateau and gardens in Kromeriz. The numismatic collection of the Archbishop chateau in Kromeriz was created especially in the second half of the 19th century, mostly as reminiscence of the former mintage activity of the Olomouc bishops and archbishops (the only ecclesiastical exponent with the right to mint coins on today's territory of the Czech Republic).
Ecclesiastical - religious coinages were mostly collected (see the offer structure). Coinage completeness of Olomouc bishops and archbishops was mainly emphasised, as for the other issuers - complex outline of coin types, especially of higher premiums. The collection was created without any respect to the amount of expended financial funds. The oldest part of the collection, ca 1/3, originates from unknown purchase sources or legacy (it is dealt with a huge part of unique and in literature not mentioned coins). The collection is an extraordinary and, up till now, preserved evidence of collecting activity in the second half of the 19th century. Acquisition activity for this collection was finished at the beginning of the 20th century.
A coupe of tough paderborn issues that you rarely see pass through any auction house:

I give away money. I collect money.
I don’t love money . I do love the Lord God.
I agree with you on the ink markings, but eh, so it went in the olden days. I suppose it might be conservable, in some cases, with a solvent. Then again, if it has been on there a hundred years, who knows?
You can remove them but you will be left with an untoned spot, which will also look wrong.
It's a shame they have written on them, but if they were mine I would leave the numbers as it is a part of their history.

that means they might not get a CAC sticker!
I really wish more museums and institutes would do this. The Fitzwilliam Museum, which has an absolutely amazing collection, has a bit of stuff online.
