That number matches a guitar made at the
Kalamazoo Plant, MI, USA in 1959.

The serial number does not give us the exact model, but a genuine Gibson solidbody made in 59 is likely to be a Les Paul Junior or a Melodymaker. Reverb prices those around US$7000 depending on condition and finish.

If it is not a fake (there are plenty of those around) and it does look that old, you could decide to get an online professional valuation from

If you do, take especially good photos of both sides of the headstock and any other Gibson logos on it.

Information on Aria serial numbers is scarce, but what there is indicates the guitar was made in the 17th week of 2000.

Dean guitars made in the USA follow a serial number pattern consisting of a 7 digit number with the first 2 numbers being the year of manufacture, followed by instrument production numbers. The serial number is found on the back of the headstock. Imported Dean guitars do not have year coded serial numbers and have to be dated by configuration and design.

That serial number would correspond to a guitar built in 1959. The model will be either be stamped on the neck block seen from inside the guitar or on the label visible through the sound hole. Martin's phone number is 610-759-2837 and they may be able to provide more specific info.
