You will as you say get more selling them individually.
However to get rid of them all quickly maybe try LCA who are currently taking submissions for an auction the first week in December although you will only have a week or so to contact them.
Tennants is another one who seem to sell alot.....Not sure if i have spelt it right but another auctioneer for them.
A dealer who may be interested who is sound is Andy at ...The Coin Gallery ,might be worth a call.
Its up to you what you would accept and most of them there are lots of.
Good luck
