You picked an interesting topic of collection. Usually collectors pick a region or just their favorites. Some collect the fresnel lens while other collect all the Christmas pieces. Can’t say I heard of anyone collecting the Winners choice as a group. Personally I think you picked a good set to collect. Their production generally ran a lot smaller than the standard issue.

John where able to come up with any production amounts for them?
Did some digging and came up with the production for these.

1. Sister island- 4,000
2. Sherwood Point- 3,500
3 Boon Island- at least 3,000
4. Sand Island- 3,000
5. St. David's, Bermuda ?
6. CAPE CHARLES, VA- 4,000
7. El Morro- less than 1,000
