A good gold-coin-making machine company should be able to give you, at least, one-year warranty. This indicates that if your equipment suddenly develops any mechanical faults within a year, you can return it for free repair. In some cases, you may be able to get an entirely new machine to replace the one you had purchased. Avoid equipment manufacturers that offer less than a year of warranty, because you can never be certain that a new machine you purchased won’t have a mechanic problem any time. You can inquire from your targeted manufacturers before committing to the purchase agreement.
