At some of the Roman Catholic churches in NYC, the chasubles of departed priests are mounted in the office area with their names and term of service on a plaque beneath.
I received a red cope from Almy which I used at ordinations; it was given to me by my predecessor, Rev. Dr. Jim Zwernemann. And I gave it to my successor, Rev. Dr. Derek Lecakes.
In terms of used albs, etc., they can be disposed, and there could be prayers spoken as those garments are taken out of service.
I have a really large collection of chasubles, copes and other garments that were given to me having been used by the Rev. Charles Werth, then the assistant to the chaplain at Valparaiso. I am still using them, but they're of first quality and I'd prefer they remain in service to Lord and Church.
