Should I open a proof set with corroded coins? [solved]

6 posts
I recently purchased a proof set from Nepal with some corroded coins. I am wondering, should I open it to add the coins to my collection.

Is it okay to open it? On the Internet the set with one or two corroded coins seems to sell for $10.
I removed the coins from my set and stored in flips, the brass coin was corroded. I think the carboard holder they have inside the plastic box is acidic... and causes the corrosion
Okay thanks! I assume we are both talking about the 1973 set.

My brass coin is the one with the most corrosion but some of the other ones as well.
Yes I have the 1971 and the 1973 sets. They both have similar holders
It's surprisingly hard to open - I did it with a hammer! :8D
It's been a while but I think I had to break the cases too :(
