Yessir, welcome to the club! Rryang, calling ahead is not a sure thing and can hurt you. If you live way out in the boonies or are trying to zero in on a stretch of road to search calling can be a guide but isn't a sure thing. I've called, been told they have halves and get there to find they were "mistaken". On at least one occasion the person who took the phone call sniped the good halves and one of my best producers became an occasional stop once I found out one of the front desk people was scooping the good halves ahead of me. By calling I was tipping him off that tellers had gotten some halves in for him to check. I still go by but I never call since I have to catch any halves as they come in before word spreads.
I have called and been told a branch has two halves, almost skipped the bank and once inside other tellers back from break start pulling out rolls. I've also called one of my frequent pickup banks last week at 5:45 and they told me they didn't have any. I then told them my name and suddenly, "oh yea we've been saving them for you come on in. " Needless to say I spend money every week on candy and snacks for my tellers and even bought my best tellers bottles of wine and liquor as rewards for all that they have done for me.
Most people answering the phone will give a quick no after asking a teller or two. Plus you are going to miss your silver dollars, old currency, little old lady's roll of dimes in line ahead of you etc. etc.
Recently I've been calling and finding many banks have $500 worth. This is the most discouraging. This time of year all banks are getting hit hard but if you enjoy the hunt then you will stay driven. If not just order boxes or buy silver,.. IMHO. It is an unusual hobby in that less is more. Right when I am discouraged and weaning myself off the addiction I hit something exciting and it rekindles the spark.
I am used to spending all day detecting and being happy finding a silver dime so getting a silver half in a day is a big step up lol. When the bank lines are too much I pop the trunk and hit the detecting trail for a walk in nature.
