This smaller than standard size of a CD 154 is embossed NO.48-40 and it has a smooth base. It is my understanding that these were attributed to Gayner production. It has a nice bubble at the upper wire groove ridge another on the crown others in the skirt. There is a 1/4" chip at the bottom of the skirt from mint condition. See my other auctions, if bidding on multiple items we will combine shipping, please wait for my invoice prior to sending payment.  No international bids please. Thank you.
