I think it is going to hurt for a while. Many small businesses (potential locations) are just not going to survive. How many barcodes will go under? This will have an impact on route operators. Many people who might spend on the hobby are going to take a significant amount of time to recover financially. Then there is the potential stigma that will be associated with “touching” things like pins - you think we had germaphobes before - this will amplify that. All these factors will affect sales of NIB pins. Plus the aging demographic of the pinball hobbyist.
I don’t know how long it will last but there will be a big impact IMHO. I hope my opinion is wrong though.
