I'm with the others here who'd commented about reputable museums !
In the event your item is displayed , you may or may not (do this as an addendum to their contract) wish to have your name included on a display 'card' for the item ... you can also have 'anon' as a 'public' choice , in this option .
I've loaned items , mostly paintings , to museums for displays/shows for up to three years , with no major incidents .
One small plus (depending upon the size '$' of insurance rider) with 'long-term' loanings of that sort , is that you can avoid paying out-of-pocket expense for the insurance that you'd usually have on the item , while it is @ home .... some agents don't want to (or won't) do this but mine are/were happy to .
It sometimes feels quite nice to share personal 'pretties' with the gen'l public !!!
There is always some degree of risk , be the item @ home or elsewhere , so I try to keep that in mind ... in the event of fire , flood , theft , damage & etc .
