Post a picture of your coin.theres lots people here that know coins.i quit watching u tub.since I found this site.
That's all I watch is youtube, hahaha, with amazon firestick on my tv. but I don't watch it for information, just documentaries, cops stuff, beatdowns. ww2, history programs, but its not a place to look for coin values.
An uncirculated 1955 cent is 3.11 +/- .13 , so from 2.98 to 3.24 is official, but a circulated coin will weigh less. Also if someone is weighing it with a scale that only shows 1 decimal place it can not be determined, so is it circulated ( worn) and what is weighing it? Photos would help answer those. But most likely no extra value, only seen a couple of Real thin planchet coins this year. Jim
If you think this is the expensive DDO we need a photo if both sides and a closeup of the date. UTube has great videos, most of them are incorrect but they are good.
