Coin price in personal collection

There are some coins in my collection that i somehow forgot to put a price tag on. I wish that there was a type of search option for this. With that, I could see the coins in my collection where I forgot to put a price tag on, without searching after them for ages.

Sorry for my bad English.

There is.  Export to excel file.  In the “Buying price” column select “blanks” and “0”.  Only those coins in your collection with no price entered will show.  Click the N# column link to add buying price.

Oh I did not know that. Thank you.
