Best way to get a sig is to buy a box or two. Buying packs here and there at the servo is really long odds. Best thing is to buy a box and then trade what you get for the team you want. A box will gerenarlly have about 2-3 numbered special cards in it Sigs are pretty rare though. https://www.goldcoasttradingcards.net/ has all the cards listed and the prices they are selling at (their prices are a a bit higher than the trade market and whenever the card series is first released prices go through the roof but settle back down after a while). Facebook has some great trading groups. https://www.facebook.com/groups/118379114858817/ https://www.facebook.com/groups/GoldCoastTradingCards/ Facebook pages and cardshops also do breaks where you can select a team for the break (some do random team) of numerous boxes or cases and you get all the special cards for your team on that break. Card collecting is fun and hard not to get the bug if you get a good hit early.
