	Crest & Seals 
	throughout the years There are very few records available that date when crest & seals ("C&S") were made. Howard Herz was able to photograph sample chip books that were kept in the United States Playing Card Company ("USPC") museum. Chips in these books were accompanied with information tags that provided, sometimes but not always, information as to date and destination. Between that and information I've gathered from other collectors and the internet, I have provided my best guesstimate as to when the different styles of crest & seals were made. Note that there will be exceptions to whatever is mentioned.  |

    1900 to 1910 
	 Inlays during 
	this period were made by Whitehead & Hoag
	("W&H") of Newark, NJ.  The 
	maker of the chip is unknown.  I have no evidence, but it is my opinion 
	that the chips were made by USPC with inlays supplied by W&H.  Note 
	that the size of the inlays vary in size.  Several of the inlays were 
	also used by W&H in the making of 
	pinbacks.  In particular, the "L" 
	(Lafayette University), Flag and 
	jockey were all featured in W&H's catalog 
	of pinbacks.  Although W&H produced colorful lithographs, the inlays 
	had a habit of lifting at the edges.  The inlay was a sandwich made of 
	paper (on which the litho was printed) and a protective celluloid covering.  
	As these dissimilar materials dried out, the celluloid would curl and lift 
	the inlay.  This was never a problem for W&H in making pinbacks as on 
	the back there was a locking ring which held the litho sandwich in place.

    1911 to 1917 
	(exception: Toledo Club 1920)  These chips, inlays included, were made 
	by USPC.  It was quite natural for USPC to make it's own inlays has 
	they already had the machinery which they used in the production of 
	playing cards.  Note that USPC chips have, for the most part, the same 
	size inlay.  Also note that chips made during this time periods had 
	holes punched into the inlay.  Having seen what happened to the inlays 
	supplied by W&H, I assume that the holes were there to provide more of a 
	grip.  Unlike W&H, USPC's inlay was a sandwich of two pieces of 
	celluloid.  Paper was not used.

    1918 to late 1940s  
	These chips were also made by USPC.  The only difference I can detect 
	is that USPC stopped making holes in the inlay.  The company 
	found it unnecessary to provide more 'grip' since the use of only celluloid in making 
	the inlay eliminated the tendency for the inlay to lift.  The last 
	known (to me, anyway) USPC chips were made for 
	
	BPOE lodge 1747 
	Farmington, NM in 1948.

    1940s to 
	approximately 1950  
	These chips were made by the Burt Company of Maine.  Chips are similar 
	to USPC chips with two major differences: 1) inlays are a bit smaller than 
	USPC inlays; and, 2) Celluloid, which was quite expensive, flammable and toxic to 
	work with, was replaced with plastic.  Celluloid developed a patina and 
	darkened over time.  The plastic inlays of Burt, for the most part, 
	remained clear as the white inlays below have shown.

    Approximately 1950 through 
	1960s  In 
	these Burt chips, the protective plastic covering appears to be thinned out 
	quite a bit.  During this time period Burt made many of the chips for 
	Nevada casinos.  Unlike the earlier Burt chips which had rounded edges, 
	most of these later chips had square edges.

    1970s  
	Imagination and style appear to be in short supply in Burt crest and seals made 
	during this time period.  These chips, in my opinion, are the least desirable 
	C&S.

    1990s to present 
	The following C&S were 
	made be Atlantic Standard Molding, the company that succeeded the Burt Co.  
	Atlantic Standard's web name is 
	PokerChipsOnline.com.  Most chips made during this time period were made for personal use or 
	advertising.  It is clear that the inlays by ASC are more colorful then 
	previous Burt chips.
