The appraisal at the end of the video says "$2,375" according to the transcript (was watching without audio) and the sample appraisal (which I guess as your sibling pointed out was just meant as a sample of what an appraisal would look like, in which case I think it would have been better form not to include actual numbers) lists $2150 which is close to that value so I assumed that's the actual appraisal.
Given that the sample actually shows a ring and refers to it in the full text, that's obviously not referring to the object but now I'm wondering about the $2,375 figure in the transcript. Is that just a really bad auto-transcription error?
