1)does your group offer different varieties?
I believe there are three styles - a semi-crown set and crown set (both in 10k gold) and then a semi-crown set in gold electroplate. Honestly, I'm not sure what the difference is between a semi-crown and a crown set.
2) how much was yours
$85
3) did you get the standard or the upgrades?
I started out with the standard badge (the $45 electroplate that most collegians get), but after that badge accidently got sucked up by my vaccum cleaner, I traded it in for the crown set. It's purty.
4) is there a "pressure" in your chapter to get the more expensive ones?
No.
BTW, the official SAI terminology is "badge" although in my experience, a lot of people say "pin"
