Go to twiste quarter they have better quality

[Billnuts]

Their is a size difference

the first one is a single coin mech usually

 

 

 

 

the second is a different size hole

 

 

 

 

both are good  but usually used in two different mountings and doors..

 

unless your fresh cutting a hole for a coin mech..

 

the second listing was from twisted quarter on ebay..
