advice for new chip collectors do yourself a huge favor and catalogue your chips by tcr # included with scans after a long time collecting Im finally getting it done only about a 1/8 of the way so far did about 250 Higher end Obsoletes had to look up TCR # soon to start scanning the Nevada $1 Collection of Commons and lower end priced chips then comes the Hard Rock Collection and $5 chips & NCV it has been alot of work but in the end it will all be worth it and I will never go to a convention wondering if I already have a certain chip and end up buying a duplicate the tablet is the way to go for me very compact no more lugging binders and paperwork that gets all messed up by shows end!
