This excellent topic http://www.predecimal.com/forum/topic/8211-portcullis-varieties-on-decimal-penny/ and its more recent contributions prompted me to complete my 1p varieties survey. Some history. There are only three major articles regarding decimal bronze coinage that include details of 1 pence varieties published in contemporary magazines:- Decimal Bronze 1/2, 1 & 2 pence varieties, Coin, 25 Jan 1980 by Iain WP Dracott, K.B.Wiles and Ron Stafford, Addendum to Decimal Bronze, Coin Monthly, Oct 1984 by Iain WP Dracott, and finally, Coin Varieties: Latest Discoveries, Coin Monthly, Aug 1987, by Ron Stafford. The main points to note about these articles is that they were written by the same three people, who have cooperated on various other articles over the years, so they are aware of each others views and the other point of note is that the first two articles include an additional reverse variety that has be excluded from the third article. The excluded reverse suggests that there are two sizes of pattern on the reverse. Prior to these articles three Letters to the editor, all in Coin Monthly, Decimal Reverses, by E.B.Mackenzie dated July 1978, discusses 1972 Proof set reverses, a further letter, Decimal Reverses, from E.B.Mackenzie adds further information received from the Royal Mint regarding the 1972 proof set reverses and a final letter from E.B.Mackenzie, A Reverse Pattern, dated March 1979 discussing 1971 through 1978 proof set reverses. Data from these letters was included in the three main articles. A final article, The 1990 UK Circulation Coinage, Coin Monthly, April 1991 by P.S.MacKenzie discuses differences between circulating coinage and those in the BU and proof sets. I have looked for the different size reverses and have concluded that they don’t exist. That being the case I have continued the August 1987 series adding new obverses and reverses. An extract of the 1987 article from Coin Monthly follows: “Decimal pennies   Obverse 1 (1) 111 beads (2) 1 of date to space (3) I of ELIZABETH to bead   Obverse 2 (1) 111 beads (2) I of date to bead (3) I of ELIZABETH to space   Obverse 3 (1) 111 beads (2) 1 of date to space (3) I of ELIZABETH to space   Obverse 4      (1)112 beads (2) new portrait etc (3)last I of II to bead   Obverse 5 (1) 109 beads (2) as obverse 4 (3) last I of II to space   Reverse A (I) III beads (2) right leg of N in NEW to bead (3) thin numeral 1 below portcullis   Reverse B (1) 111 beads (2) right leg of N in NEW to space (3) thick numeral 1 below portcullis   Reverse C (1) 110 beads (2) legend now reads ONE PENNY (3) small 1 below portcullis   Summary   Circulation   1971 - 1 A 1972 - none minted 1973-1975 - lA 1976 - lA and 1B (rare) 1977 - lA 1978-1981 - 2A 1982-1983 - 2C 1984 - 3C 1985 - 4C 1986 - 5C   Unc Sets  1982-1983 - 2C                  1984 - 3C                  1985-4C 1986 - 5C   Proof Sets    1971 - lA 1972-1977 - lA and 1B 1978-1981 - 2B 1982-1983 - 2C 1984 - 3C 1985 - 4C 1986 - 5C? (not seen) NB: the reverse A Proofs are scarcer for 1972-1977, those of 1972, 76 and 77 being very scarce.   Notes     The rare circulation 1976 reverse B is very hard to find. I know of only six specimens. I found only two out of 3,681 1976 pennies checked during a sortee in 1979. If anyone should stumble upon a 1975 reverse B in change, they would have a very rare coin indeed. No one knows for sure if it even exists but the 'new reverses' first seen in the Proof sets do occur on both 1975 and 1976 2 and 10 pences issued for circulation. The earliest 1976 1 B rarity I know of was found by P S Mackenzie in late 1976/early 1977. The 1985 and 1986 circulation pennies are now extremely common, there does not seem to. be any varieties, all 1985 being type 4C and all 1986 being type 5C. The earliest reported 1985 penny was found on 22 November 1985 by Mr Symes. For the 1986 penny, the first was noticed on 14 August 1986 by Mr D Price.”   End of Article.

It can be a bit confusing when discussing pointings. Which direction is one looking from? I always follow the rule of “as you read it”, so on a 1p reverse you read the NEW PENNY from the centre of the coin looking towards the rim. For example, taking the letter N of NEW you would sight from the bottom of the right hand (RH) leg, to the top of the leg and onto the boarder bead (bb) beyond. 1.      One would then say the leg points to the centre of  a boarder bead (to bb), or 2.      slightly left  or slightly right of the center of a boarder bead (sl or sr bb), or 3.      right or left of a border bead (rt or lt bb), that is to the edge of the bb or very slightly into the space between boarder beads , and finally, 4.      points between two boarder beads or in other words to the center of the space (to sp).    When looking at the number 1, then the orientation is from the rim to the centre (as that’s “how you read it”).   Boarder beads (bb) and teeth. Beads are just teeth that don’t touch an internal or external boarder or rim.   Portcullises. The first report of variations in the portcullis were made by Dr R.M.Owens to Coin News in January 2013. These have become known as type 1 and type 2 portcullises. This confuses the situation slightly as the variations refer to the representations of the rivets used on the portcullis and not the actual portcullises themselves. There are two kinds of portcullis, that which was used on circulation coins from 1971 through to 1981 and on proof coins for 1971 which I call type 0 and the second type used on all other circulation, proof and brilliant uncirculated set coins and this is known as types 1 and 2.   Type 0. The vertical and horizontal parts of the portcullis do not touch each other and the vertical parts are detached from the horizontal rod above them. The rivets are in relief and the positioning of the rivets is regular and even. Type 1. The vertical and horizontal parts do touch each other and the vertical parts do touch the horizontal rod above them. The rivets are in relief and the positioning of the lower two rivets on the central vertical bar varies slightly. Type  2 The vertical and horizontal parts do touch each other and the vertical parts do touch the horizontal rod above them. The rivets are incuse and and the positioning of the rivets on the central vertical and lower horizontal bar vary. Expanded Summary Obverse and Reverse pairing   A note regarding the reverse designations. I have added the portcullis type and rivet position subtype to the familiar reverse designation.   Summary   Circulation   1971                - 1A0 1972                - none minted 1973-75           - lA0 1976                - lA0 and 1B0 (rare) 1977                - lA0 1978-81           - 2A0 1982-83           - 2C1 1984               - 3C1 1985                - 4C1 1986–88          - 5C1 1989                - 7C1 1990-91           - 5C1 1991-92           - 5D2b and 5C2b 1992                -5F2b 1993                - 9D2b, 9F1 and 9F2b 1994                - 5C1, 5D2b and 5F1 1995-97           - 5D2b 1998-99           - 10Db2 2000                - 11D2c and 11F2b 2001-07           - 11F2b 2007-08           - 11F1 2008                - 11F2b                BU  Sets      1982-83   - 2C1                     1984        - 3C1                     1985        - 4C1                     1986-87   - 5C2a                     1988        - 6C2a                     1989        - 7C2a                     1990        - 8C2a                     1991-92   - 8E1                     1993-97   - 8E2b                     1998-99   - 10 E2b                     2000-08   - 11E2b                     2008        - 11F1                                          Proof Sets    1971        - lA0 1972-76   - lA? and 1B1 1977-81   - 2B1 1982-83   - 2C1 1984        - 3C1 1985        - 4C1 1986-87   - 5C2a 1988        - 6C2a 1989        - 7C2a 1990        - 8C2a 1991-92   - 8E1 1993-97   - 8E2b 1998-99   - 10E2b 2000-07   - 11E2b 2008        - 11E2b and 11F1                    I will add pictures of the various obverses, reverses and portcullises tomorrow (with luck!).
