Putting Proofs In Albums - How To Avoid Marring?

I like the idea of removing the back slide and putting them in through the back (instead of pushing them in from the front). At least don't have to worry about "pushing" on the obverse of the coin by doing that, which is the side that you will see in the albums most of the time anyhow. Also, the acetate slide won't have to slide over the obverse, which should help decrease the chance of marring while sliding the cover back in. I figure you could easily mar a coin when pushing the slide in.

For what it is worth, I also usually use a microfiber cloth when I am putting coins in my albums.

I don't know how I'll get inside the ziplock with the coins to put them in their album. Even so, there will be humidity inside the bag which will condense.

The main problem I have had with Danskos is the hole is too big and the coins will fall out if I don't put strips of paper to hold the coins in
I have had no problems at all with my Whitman albums
