No, a counterfeit pen may not be effective for detecting counterfeit 1969 100 dollar bills because they were printed with the same type of paper used for genuine bills at the time. It is recommended to use other methods such as ultraviolet light or consulting with an expert for verification.
Counterfeit detection pens contain a special type of ink that reacts with the starch in common counterfeit paper to create a dark mark. When this pen is used on genuine currency, it will not leave a mark because the paper used in authentic currency does not contain starch. This simple test helps to identify counterfeit bills quickly and easily.

In QTP, a Run-Time Object (RO) is the state of an object QTP is using in some capacity during a test. The state of an RO is dependent on the activity of the test. An RO differs from a Test Object in that the properties of the object may change once the application is put under test. These changes are the reason for differentiating between Test time and Run time.
Test charge is always a test charge. The electric field does not depend on the test charge. Usually we assume the test charge to be one coulomb positive charge. Though you make it half, it would never affect the field around the primary charge

I just marked a 1950 ten dollar bill with a counterfeit detector pen. The ink turned black indicating it was fake. It says on the pen that it is 'effective on most currency series 1959 and after.'

Because the 1800 Draped Bust dollar has 5 major known varieties, unfortunately it has no group characteristics that would give it away as a counterfeit. You can check some basic things such as weight (26.96g) and the magnet test, also look at the edge for a seam and check the surface for granularity. Show it to other collectors and dealers and see what they think. But the best thing is send it to one of the top grading services.
The Rubin test is used to test the authenticity of paper currency. It involves using a special pen that reacts with the starch in wood-based paper to identify counterfeit bills. If a bill passes the Rubin test, it is considered likely to be genuine.
