Following our rash of robberies, our insurance company served up another blow when our premiums came due: the announcement that a deductible of $500 would be placed on both our homeowners and valuable-items policies. It did not matter that the previous purse-snatching and holdup produced only minor claims of $92 and $41, respectively.

Nor did it concern anyone that for 12 years our record was unblemished except for a claim of $42.40 for an amethyst that fell out of a ring. Loss from the New York incident was considerably higher: $1,530. Still, I couldn't help thinking that during those 12 years, we probably paid four times that much in premiums.

Most of the $1,530 claim was due to the loss of three pieces of jewelry. I do not normally carry my gems in a handbag; however, in 1981 the insurance company added to our valuable-items policy a "travel" provision, which denied coverage to jewelry unless, at the time of loss, it was either in our personal possession or locked in a hotel safe.

Insurance agents and other authorities differ on their opinion of quality of service we have received. Some say our agent should have interceded for us, made the case that we were victims of circumstance and fought the increased deductible. Some say we, the insured, owe it to ourselves to select an agent who has a good rapport with company underwriters. (How we arrange that selection they do not say.)

But all who commiserated with us agree we have little recourse now that the deed is done, and hereafter should not even think of submitting anything but important claims. With out new $500 deductibles on both policies, that is advice we will be forced to follow.
