Front yard of 152 Court St, (3A)... ask for permission from the business in there...tell them you used to live there in the 70’s.
And the house directly behind it, a big old blue house, converted into a duplex, the back yard is guaranteed to have old coins.... get permission from them. My old backyard is now a massive parking lot, you should be able to access the back yard of the blue house, which is on Alden St.
