Sad to say, but coin collecting is beset by counterfeits and thieves, anymore. For the price of a single fake coin, you can get a very necessary tool, the digital scale, to weigh your potential purchases. Sounds like you have one, and are using it, a good thing to do.
You'll spend about a $100 to $150 on a decent scale. The mechanical arm scales are OK, but slow to use and their cost can approach an electronic scale price.
Here is one scale, a common Dillon scale for reloaders. It weighs in Grains and Grams, as selected, cost $140.
