By Type would be very nice, show me all those rolls in one lot!

I suggest a give away!

I suggest the option “by feel”. Do what feels right in your heart!

I would like to see a few display boxes of a copper, silver, gold, platinum sets.  With a dolphin or mantis sticker in the window

I'm a big fan of mixed lots personally, but they have the inherent drawback of most bidders only being interested in a limited selection of what is being presented. When you run auctions by type, you're more likely to get more for the lot since someone is likely to be interested in everything being presented. I guess it depends on your aim as an auctioneer!
