My copy of Renaissance had three different bundles. However a different print run may have been collated such that two bundles could be the same. You will have to check to see what you after you have sorted them.
In addition to the mats, coins, and cubes, you should have these cards —
A) 1 each of the following (Artifacts and Projects):
Flag
Horn
Key
Lantern
Treasure Chest
Academy
Barracks
Canal
Capitalism
Cathedral
Citadel
City Gate
Crop Rotation
Exploration
Fair
Fleet
Guildhall
Innovation
Pageant
Piazza
Road Network
Sewers
Silos
Sinister Plot
Star Chart
B) 25 different randomizers -- backs are different than the regular kingdom cards.
C) 10 each of the 25 different kingdom cards.
Acting Troupe
Border Guard
Cargo Ship
Ducat
Experiment
Flag Bearer
Hideout
Improve
Inventor
Lackeys
Mountain Village
Old Witch
Patron
Priest
Recruiter
Research
Scepter
Scholar
Sculptor
Seer
Silk Merchant
Spices
Swashbuckler
Treasurer
Villain
I haven't looked in the third bundle yet, but the bundle I sleeved had Border Guard exposed, and all the cards in order down to Lackeys, I think. The second bundle did as well; they appeared to be all the same cards.
Everything else is there; mats, coins, and project cubes. It really does look like whoever packed it (assuming its packed by a person and not a machine) grabbed 2 of the same bundle instead of 1 of each.
The one odd thing is that 5 of the 6 mats were punched out and sitting in almost a nice stack with the coins and such on the tray. I know its not uncommon for the mats to break loose during shipping but it looked like they were stacked by hand.
I'll wait and see what RGG responds with. Thanks for the insight.
