OK, here is your decision! LOL for my comments in the other threads. Glad you settled on these as they are a special set that I had a hand in putting together.
You have gotten LOTS of great advice. Only reason I'm going to add to it is because I've been playing the exact games you are planning on. I play almost exclusively nickel / dime blinds cash games. EVERY cash set I own has nickels. (I have 3 that are playable and 3 more that I'm putting together) I play with family and friends who mostly play very little poker, and who don't know all the intricacies that PCF people do.
Having said all this - I PROMISE you - if you are trying to keep numbers down, you don't need more than 100 nickel chips. But still, order 120 so you have extras or in case a couple get broken in shipping. Same with every denomination. Even in a nickel / dime game, the quarter is still the workhorse chip. And once your guys get a little experience under their best, the $1 will also be a secondary workhorse chip. Think this way - You only need 2 chips to limp in. After that, most raises will include quarters. If you limp at 10 cents, then someone raises to a quarter and you call, you're going to pull back your nickel chips and put in a quarter. 10 nickels per player is plenty.
Do get 200 quarters. You got that right.
Bump your $1s up to 200 or more. If (WHEN) your game grows, you'll be glad to have a few more.
Bump the $5s up to 100. And DO get the $20s, if for no other reason than they are the coolest chip in the set! Seriously, even on a budget, adding in an extra 100 chips is $28. You will kick yourself and regret it if a year from now your guys want to play a little bigger and you don't have enough chips. For color variation reasons, it's always best to order ALL the chips you think you might need at the same time. Adding on from a different batch could result in chips with two different shades of the same color.
And finally, if you are not in a huge hurry to place your order, PM me and I will set you up with some samples. I have some leftovers from the group buy and I think I can get a padded mailer to you in Portugal for a reasonable shipping amount. My treat to a new chipper. Just no promise how long it might take.
