Lol.
@detroitdad voted 'No' to mixing 39mm and 43mm.
One other thing. Most people are okay with the big denoms being oversized. Personally, I'm not a fan... We don't get many $25's or $100's in play.
The last time we played on the Aurora Star set, I had 6 barrels of 25¢, $1 and $5, but I had like four oversized $20 chips... It felt awkward to stack them on top of a barrel of $5s because they weren't the same size and I didn't want to start a separate barrel for just 4 chips... so I just kinda stacked them on top across multiple barrels.
Compare that to having the smallest denom be undersized... There are plenty of the small denom on the table, so you have the chance to make a full barrel of that chip, if not multiple barrels.
It feels less awkward to me to have an undersized lowest denom than it does to have a oversized highest denom.
Ideally, all the same size. But if you're going to mix sizes -- at our stakes -- I'd prefer the lowest denom to be undersized.
JMHO.
