Yes, with 90 different two-digit numbers to choose from, HP have re-used some of them several times over, confusing collectors forevermore.
TI-30, anyone?

And 10 is especially overused. In order of introduction, there are:
HP-10 (sometimes called the 10A)
HP-10C
HP-10B (yellow labels)
HP-10B (green labels)
HP-10BII (Gold)
HP-10BII (Silver)
HP-10BII+
Not surprisingly, they are generally worth progressively more today as you move up the list (newer to older) though 10B w/yellow might be the cheapest due to the huge number of them sold.

But
TI-30 .... I don't even know about it
It was just an example of a model name abused a gazillion times.
