Quoted from HighVoltage:I've resorted to keeping some larger sums in safety deposit box. Never know when some special pins might go on sale!
If you're someone who buys and sells pins often, that is probably the best, easiest, fastest, hassle free and safe option. Better than putting it under the mattress or stashing it in the house somewhere. The best deals go fast. I would advise that when you are "looking" for a used pin to at least call your bank to know what their policy is. It seems from posts here that the individual branches make their own policies on this. Guessing that the larger towns/cities have the larger cash withdrawal limits.
Bump for the pin sale ... we're trying to help! The ad is getting more attention than normal.
