We prestacked our M&M tubes and put them in checked luggage without any problem.
I know this is kinda off-topic but . . .
We recently got back and organized our pressed penny albums. (BTW - We really like the larger books with 64 penny slots and no quarter slots.) We have the following WDW pressed pennies and are looking to possibly trade with anyone who has duplicates of pennies we don't have. The pennies we have available are:
Country Bear Jamboree, (Zeke), Magic Kingdom (3)
Country Bear Jamboree, (Big Al), Magic Kingdom
Minnie Mouse (Full Face), Magic Kingdom
Big Thunder Mountain Railroad (Train), Magic Kingdom
Buzz Lightyear (Full Figure) (2)
Splash Mountain (Mickey, Pluto, Goofy + In Log)
Splash Mountain (Brer Rabbit), Magic Kingdom
Jungle Cruise (Boat), Magic Kingdom (2)
Adventureland (Safari Mickey and Shere Kahn), Magic Kingdom (2)
The Lion King (Pumba) 4 of 7
The American Adventure (Uncle Sam Mickey), World Showcase, Epcot
Mexico (Mickey in Sombrero), Epcot
Lilo & Stitch (Stitch), 4 of 7
Animal Kingdom (Safari Goofy w/ Camera)
Magic Kingdom (Eeyore)
Frontierland (Cowboy Mickey), Magic Kingdom
Some of them are very clean, some old and dirty, most pre-82.
PM me if you have a trade offer. Thanks.
