I have a question. I have a bunch of Polish-Lithuaninan Commonwealth coins which are in rather bad condition but still I can distinguish them by general type, these are Solid coins:
1) with knight rider type - KM#50
2) with Polish eagle type - KM#110

I can' read neither any dates on them nor any mintmarks or mintmasters' initials to distinguish between them by mint and date. My question is as follows: how do I put them to Numista into My Collection records if I do not have this info? Is there any general way of cataloging such coins into your collection to keep track of them? Any help will be welcome
Thank you!
Alex
