Massive vintage to now brooch/pin lot

There are 45+ brooch/pins in this lot with the majority of them being in decent pre-owned condition.
The second photo is of pieces that are not in good condition and could possibly be repaired or could be used for parts.
A few have makes and or symbols.
No testing of materials has been done!
Some of these seem to have decent value of $25 and up but I don’t have the desire to sell separately. The 11th photo is of what I believe to be a Penca De Balagandan brooch but it is broken. To my understanding the charms can be removed to sell individually!? This appears to be a pricey piece in good condition but unfortunately I’m not sure if it could be repaired. The last photo is an interesting piece as well but again it is not in good condition. It does have verdigris and will be packaged separately from the others.
I did not inspect these pieces very well so I may have missed flaws. I do not want to sell individually and this lot is sold as an as is, no returns lot.
