The 250 has limitations, but it is not junk. Now go find some old turn of the century houses, and get permission to check under the huge old evergreens in the yard, the garden, whatever. Do not be discouraged if some say no, or are a bit snarky. Many folks will say yes if you are friendly and explain that you will be neat and careful. You will almost immediately find older coins and relics. Some old houses have many coins, some have next to none. If an old person comes to the door back off or step down and speak gently to them. Gentle and friendly gets more permissions than too close and bold.
