Yep, I think that's quite possible, Gene. I have the inaugural chip too, which I was told was used on the Symphony, and the regular $5, shown in the original post, that I was told was used on the Harmony. Both are red, house mold chips with the same purple and yellow edge inserts. I think you're right: Caesars Palace at Sea is using the same chips on both boats.
