Are you thinking of selling them? As I cannot see any for sale or sold.
How many? If it is a large collection, then, although it narrows your field of buyers, a collection only, I would advise.
If it is a few, then bubble wrap each place cardboard between each, place in large box with filling of some sort all around. Would imagine then that postage would be hefty, and Royal Mail do not compensate for any breakages, I believe few carriers do either, thus, a collection only probably is best.
